John Travolta has reflected on some of the near-misses in his career, including the role played by Tom Hanks in 1984 romcom Splash.
Speaking to Kevin Hart on his streaming show Hart to Heart, Travolta said the part in Ron Howard's famous comedy was written with him in mind.
The 67-year-old star joked that he can "take responsibility" for the careers of several stars who took roles he wasn't able to do, including Tom Hanks and Richard Gere.
He said: "The role in the Hanks film called Splash was written for me. But then we wouldn't have Tom Hanks, so let's have Tom Hanks."
Hanks ultimately took the role, in which he portrayed a man who falls in love with a woman who is secretly a mermaid — portrayed by Daryl Hannah.
The film was a success at the box office and with critics, securing an Oscar nomination for Best Original Screenplay and helping to take Hanks's career to the next level.
Travolta said he was also unable to take on roles he was offered in the Terrence Malick film Days of Heaven, which went to Richard Gere, and Hal Ashby's The Last Detail — ultimately taken up by Jack Nicholson.
He revealed that there was a small group of actors at that time in the late 1970s and early 1980s who were routinely approached for similar roles.

"This is the irony of it, or the interesting part of it, I should say. There was very few of us. Now, there's a tonne of people competing," said Travolta.
He added: "It's much more difficult to establish yourself now in any aspect — movies, music.
"It was just Richard Gere, myself and Treat Williams up for most parts. So if I didn't get it, one of those guys would. And then Tom was a few years later."
He added: "Those roles would get interchangeable, depending on what was happening. So in some ways, in Vegas, what's a one out of four chance?"
Travolta was offered numerous projects during this time period, following his success with Grease and Saturday Night Fever in the 1970s.
He missed out on hits including An Officer and a Gentlemen and American Gigolo, which both went to Gere.
His career subsequently declined throughout the latter part of the 1980s, until his resurgence in the wake of his Oscar nomination for Quentin Tarantino's 1994 thriller Pulp Fiction.
