#04 Leonard Nimoy & William Shatner – Star Trek
Captain Kirk and Spock looked like the perfect space duo on Star Trek, but Leonard Nimoy and William Shatner didn’t always see eye to eye in real life. Shatner has said they started as rivals, each trying to get more attention on set. Over time, that competition turned into a kind of sibling relationship — they’d argue, laugh, and still have each other’s backs. Their friendship wasn’t perfect, but it was as memorable as their on-screen adventures.
