Next up is one of the most famous TV show sin history—Star Trek. Although onscreen they cooperated perfectly well, George Takei and William Shatner didn’t get along in real life (and still don’t all these years later). Nobody remembers exactly how the feud got started. While Shatner claims it was due to an argument over a close up during filming, Takei says that Shatner is just jealous of Sulu’s growing popularity. These two actors might be living long, but their relationship certainly isn’t prospering.
