John Travolta has credited his faith and fellow members of the Church of Scientology for helping him recover from the death of his teenage son Jett in 2009.
The 16 year old died from a seizure during a family holiday in the Bahamas, and, in a new live onstage interview with British Tv personality Barry Norman in London, the movie star called the tragedy "the worst thing that's ever happened in my life".
He added, "The truth is, I didn't know if I was going to make it. Life was no longer interesting to me, so it took a lot to get me better.
"I will forever be grateful to Scientology for supporting me for two years solid, I mean Monday through Sunday. They didn't take a day off, working through different angles of the techniques to get through grief and loss, and to make me feel that finally I could get through a day."
During the 90-minute chat at the Theatre Royal Drury Lane, Travolta also discussed his career highs and lows, explaining that, "It got a little complicated for a few years," when he failed to land decent roles prior to his rebirth in Pulp Fiction.
He said, "A lot of things added up to a five-year period that wasn't so good for me... There were people who were much hotter than me who wanted the role, but Quentin (Tarantino) put his career on the line and refused to make the movie without me in it."
During Sunday's (16Feb14) A Conversation with John Travolta, which came just two days before the actor's 60th birthday, he also showed off his impression of Sir Sean Connery and gave dancing lessons to a handful of lucky fans in the audience.
The celebrity pilot's West End debut ended with the presentation of an airplane-shaped cake.
