#1 The Rock in Star Trek: Voyager (2000)

The Rock. The Great One. The Brahma Bull. The Most Electrifying in Sports and Entertainment. Future WWE Hall of Famer. Hollywood Superstar and the list goes on. It's hard to fathom that The Rock has been a massive success in Hollywood and achieved more than anyone thought possible. He paved the way for Batista, John Cena, CM Punk, and so many others who will follow suit in the year to come.
The Rock in Star Trek may not seem like a natural fit for the charismatic multi-time WWE Champion. But considering that The Rock as an actor was still not taken seriously at the time. Most of his roles on Television were limited to brutes. His role in the episode titled 'Tsunkate' marked The Rock's entry into science fiction territory.
The Rock is fine in the episode as a Gladiator taking on Seven on Nine and even delivers a Rock Bottom at the end of the fight. With that said, the WWE Superstar's role is a glorified cameo limited to an extended fight scene.
It also highlighted the popularity The Rock was enjoying at this point in his career. At that time, WWE SmackDown was featured on UPN, which also broadcast Star Trek: Voyager. So, in essence, the guest appearance was a cross-promotional exercise. It was estimated the episode was the highest-rated of the season, which was Voyager's sixth.
In short, it was an interesting start to The Rock's acting career as he eventually became one of the biggest movie stars on the planet. He will go down as one of the greatest WWE Superstars of all time and also for his role in creating pathways for young WWE wrestlers to follow in his footsteps.
