#5 and #4 Crush and "Fake Undertaker" in Khiladiyon Ka Khiladi (1996)

In one of the more head-scratching appearances by WWE Superstars, both Crush and Undertaker were in a Bollywood movie back in 1996. Let's be clear; this was the Fake Undertaker played by Brian Lee. He featured in a match in The Undertaker vs. Undertaker match at WWE SummerSlam in 1994.
Look who just shut down all of Tony Khan's critics! More HERE.
It's hard to describe this film as Bollywood films in those were still caught in Masala-Mix cinema, which would just be described as a mix of action, comedy, and tragedy. The film starred Akshay Kumar, Rekha, Raveena Tandon, and Gulshan Grover. The film depicts illegal wrestling matches being held in New York, complete with rings and entrances.
Of course, this is set in the crime world with Akshay Kumar having to rescue his brother from this underworld and eventually goes one-on-one with 'Undertaker.' Also, it should be mentioned that this Fake Undertaker murdered Crush at the beginning of the film while Akshay Kumar boldly kills Fake Undertaker at the end of the film.
To get into specifics would be like entering The Matrix. But for WWE fans who are interested, they will be treated to wrestlers dubbed over with Hindi, watch drama, heel turns, and double-crosses. In wrestling terms, it was like an episode from the WWE Attitude Era.
#3 Kevin Nash in Teenage Mutant Ninja Turtles 2: The Secret of the Ooze (1991)

Former WWE Superstar Kevin Nash has had quite a career in both pro wrestling and entertainment. He has been seen in movies like The Punisher, John Wick, Magic Mike, Magic Mike XXL, Rock of Ages, and The Longest Yard. But before that and even his WWE and WCW stardom, he made his film debut in Teenage Mutant Ninja Turtles II: The Secret of the Ooze.
At this point, Kevin Nash was languishing in the mid-card in WCW and was put into roles like Oz and Vinnie Vegas. It wasn't until going to WWE in 1993 and becoming Diesel did Nash see his star rise. But Nash's role in the film is limited. He plays the Super Shredder after Shredder has ingested the ooze for himself.
He's under a mask and destroying a boardwalk before being crushed underneath it. It's safe that Kevin Nash did move up in the world after that.
