Life hasn't been easy for Tom Cruise lately.
In a sit-down with German TV network ProSieben (via Germany's Bunte magazine) while making the press rounds for his new sci-fi blockbuster Oblivion, Cruise confessed to being taken aback when the 34-year-old actress decided to end their five-year marriage abruptly last June.
"I did not expect that," the Hollywood star said.
Holmes announced their separation on June 29—five days before Cruise's 50th birthday. After speedy negotiations, both sides' lawyers reached a settlement two weeks later that gave Katie custody over their 6-year-old daughter Suri and Tom generous visitation rights.
But Cruise revealed the split gave him "an incredible amount of time to reflect" as he celebrated his milestone birthday.
"Life is a challenge," admitted the thesp. "To be 50 and have experiences and think you have everything under control, and then it hits you—that's what life is…Life is tragicomic. You need a certain sense of humor."
Now that he's single again, Cruise has thrown himself back into work.
Aside from Oblivion, which hits theaters on April 19 and costars Morgan Freeman, he's toplining another sci-fi adventure, All You Need Is Kill, directed by Doug Liman.
And Cruise also announced during a recent appearance on the U.K.'s The Graham Norton Show that he's "working on the story" for a fifth Mission: Impossible film, though he declined to divulge any more details.
