Why Caitlin Snow From The Flash Looks So Familiar

Ever since it debuted in 2014, "The Flash" has amassed one of the most unique and beloved supporting ensembles in the entire Arrowverse. Obviously, Grant Gustin's Barry Allen is the star of the show, but characters like Cisco Ramon (Carlos Valdes) and Iris West (Candice Patton) have remained consistently likable presences on the show as well. Even villains such as Reverse-Flash (Tom Cavanagh/Matt Letscher) and Captain Cold (Wentworth Miller) have become beloved members of the overall ensemble for many fans.

In that regard, one character who continues to stand out as a fan favorite is Caitlin Snow a.k.a Killer Frost. One of the earliest additions to the universe of "The Flash," Caitlin is a S.T.A.R Labs scientist who struggles with her villainous side after developing ice powers. Why exactly does Caitlin Snow look so familiar? Audiences may quickly recognize her because she is portrayed by a seasoned film and TV veteran who has maintained a consistent presence on the big and small screens for well over a decade, developing a fascinating IMDb page in the process. Given her long history in Hollywood, let's take a look at some of the biggest and best roles to her name.

Her first superhero project was 2005's Sky High

While Danielle Panabaker has arguably become best known for her work in the Arrowverse, that franchise is not her first major foray into superhero filmmaking. In fact, she previously appeared in the 2005 superhero cult classic, "Sky High." The film starred Kurt Russell and Kelly Preston and provided a launching pad for many other up-and-coming actors who would become stars of today, including "10 Cloverfield Lane" star Mary Elizabeth Winstead and "Succession" actor Nicholas Braun, in addition to Panabaker.

In "Sky High," Danielle Panabaker portrays Layla Williams. She is a student at Sky High and a friend of Will Stronghold (Michael Angarano). The film presents her as a vegetarian with the ability to control plant life. "Sky High" was released in 2005 and received mixed to positive reviews upon its debut (via Rotten Tomatoes). However, it underwhelmed at the box office, bringing in a domestic total of $64 million during its theatrical run.

She was a killer in Mr. Brooks

Danielle Panabaker has appeared in numerous thrillers and horror movies throughout her career. While this often saw her running from killers, one particular film let her be the aggressor and take victims of her own. Specifically, she played Jane Brooks in the 2007 thriller "Mr. Brooks." The film starred Kevin Costner as the titular serial killer, an unassuming and seemingly successful businessman harboring a deep compulsion to kill. Jane is introduced as his college-aged daughter, with the film ultimately revealing that she has inherited his need to kill.

At this point, "Mr. Brooks" remains a one-and-done thriller for Costner and the supporting cast. However, there were reported plans to turn the property into a full-blown franchise based on the success of the first film. In fact, in an interview given by director Bruce A. Evans to Bloody Disgusting, the potential sequel would've taken a page from the "Taken" playbook and seen Brooks' wife and other daughter kidnapped, resulting in kidnappers drawing the ire of not only Kevin Costner's Brooks but also his increasingly dangerous homicidal daughter. However, 15 years later and there is still no sign of a sequel.

She was hunted by Jason Voorhees in the Friday the 13th remake

The Arrowverse is not the only major franchise that Danielle Panabaker has appeared in throughout her career. In fact, in 2009, she appeared as Jenna in "Friday the 13th," which served as a loose remake and soft reboot of the Jason Voorhees franchise. Jenna survives much of the film alongside Jared Padalecki's Clay, but she ultimately finds herself run through by Jason's machete during the climax of the movie. This is a significant rug pull, as Jenna is ostensibly positioned early in the film to serve as the final girl of the remake – until the film decides to take her off of the board and focus on Clay and his sister Whitney (Amanda Righetti).

Jenna's demise in "Friday the 13th" went through an evolution before the filmmakers landed on the final version of her death. In fact, Panabaker opened up about this in an interview with Shock Till You Drop back in 2009 and confirmed that Jenna not only lived longer in the original cut of the movie, but she also got to fight Jason with a fire extinguisher in the moments leading up to her death.

She was killed by The Crazies

The year after being viciously murdered by Jason Voorhees in Camp Crystal Lake, Danielle Panabaker went on to join yet another reimagining of a classic horror property. Specifically, she took on the role of Becca in the 2010 remake of George A. Romero's "The Crazies." The film follows a group of survivors trying to make their way out of their Midwest town when a bioweapon infects their water supply and turns the entire population into homicidal maniacs. Panabaker's Becca makes it through a large portion of the movie — unlike her boyfriend. However, she is brutally killed by an infected when a noose is wrapped around her neck and she is pulled from the back of the car when her group of survivors enters a car wash to hide.

Upon its debut in February 2010, "The Crazies" received mixed to positive reviews from critics (via Rotten Tomatoes). It was widely praised for its economical storytelling and good use of tension. One particular element called out in several of the positive reviews was the strong performances of the film's cast. In addition to Panabaker, "The Crazies" also starred Timothy Olyphant, Radha Mitchell, and Joe Anderson.

She had an affair with Roger Sterling on Mad Men

John Slattery's Roger Sterling had a number of affairs and flings over the course of his tenure on AMC's "Mad Men." One such fling was Danielle Panabaker as Daisy in the 2013 episode titled "For Immediate Release." In the episode, Daisy is introduced as a stewardess who Sterling takes to bed for an evening. When she attempts to leave the next morning, he convinces her to stay with him by revealing the recent death of his mother, urging her to keep him company.

Panabaker's role as Daisy on "Mad Men" is not her largest small-screen role, but it was one of her first major roles in the world of prestige television and arguably marked a notable graduation to adult storytelling from her earlier years as an actress. Panabaker's episode of "Mad Men" aired in May 2013. Less than a year later, she would appear in "The Man Under The Hood" on "Arrow," which would officially introduce her recurring role as Caitlin Snow in the Arrowverse.

She portrayed Penny Cole in Justified

Finally, we come to yet another prestige drama that featured supporting performances from Danielle Panabaker around the time at which she joined the Arrowverse and became a full-fledged actor in the superhero community. She portrayed Penny Cole in the beloved FX series "Justified." The series followed Timothy Olyphant as Raylan Givens, a U.S. Marshal who brings a unique style of crime-fighting to his hometown in Kentucky and comes into conflict with a number of deadly criminals along the way.

Cole is introduced in Season 5 of "Justified" as a young woman living out a sentence in a women's correctional facility. During her time in the series, she befriends Ava Crowder (Joelle Carter) while she is incarcerated in the same facility. Panabaker would go on to play Penny Cole for a total of six episodes throughout her run on "Justified," before the character was brutally stabbed to death by another prisoner in the 2014 episode titled "Starvation." As such, don't expect her to show up in the highly-anticipated "Justified" revival.
