Tom Cruise has spoken about his divorce from Katie Holmes, admitting that the separation took him by surprise.
The Hollywood star was being interviewed by German TV station ProSieben for the premiere of his new sci-fi film Oblivion when he was asked about the relationship.
The ex couple, who have six-year-old daughter Suri together, announced last year that they were separating after five years of marriage.
"I didn't expect it," Tom was quoted as saying.
The star said after the split he had "an unbelievable amount of time to think".
"Life is a challenge," said Tom, who was previously married to Nicole Kidman and Mimi Rogers.
He added: "To be 50 and to have experiences and to think you have a grip on everything, and then it hits you - this is it, what life can do to you,"
Us Weekly quotes him as telling the TV station: "Life is a tragicomedy. You need to have a sense of humour."
