Actors who were in both Star Trek and Star Wars

Star Trek and Star Wars are often looked upon as two sides of the same sci-fi coin, the former revered for its philosophical approach to the genre, the latter for putting that genre on the mainstream map. In truth, both franchises probably owe their continued existence to the other: George Lucas admitted that Star Trek "softened up the entertainment arena so that Star Wars could come along and stand on its shoulders," whereas William Shatner conceded that Paramount only became interested in giving Star Trek a real shot after the first Star Wars picture took the movie world by storm in 1977. The two genre juggernauts jostled for supremacy in the decades that followed, and a healthy rivalry developed between the respective fandoms, giving birth to the idea that people ought to pledge allegiance to one franchise over the other, an idea that the following actors chose to ignore entirely.
