Hugh Jackman realized at a screening for his new film "Real Steel," that he forgot to explain the dynamics of on-screen love interests to his 11-year-old son Oscar.
"I forgot to tell my boy that he was about to see his dad kiss another woman and explain that experience because it was the first movie of mine that they've been to," Jackman told OnTheRedCarpet.com co-host Rachel Smith at the film's Los Angeles premiere. "So literally, the scene came on and I was like, 'Oh no' and I said, 'Deb, Deb, Deb' and she was like 'Oh right.' so she's looking and Oscar just looks straight up and he goes, 'Wow, Dad, you're going to be in trouble.'"
Jackman and his wife, Deborra-Lee Furness, married in 1996 and adopted two children, Oscar and Ava Eliot, 6.
"Real Steel" takes place in 2020, where robots have replaced humans in the boxing ring and Jackman plays a retired boxer turned small-time promoter who sees potential in a discarded robot. In the process of training his new champion, starts sharing a life with his 11-year-old son.
"The different thing about this movie, 'Real Steel' is that this is an action movie where I really don't do that much action, which is always kind of nice," Jackman joked. "I was like, 'Oh good, away you go, robots!' The robots are amazing -- they're huge, they've got fire, they go crazy and I'm controlling them from the corner, so it was kind of nice."
The film also stars Dakota Goyo as Jackman's son and "Lost" actress Evangeline Lilly as Jackman's love interest.
"There are a couple moments where I get in some skirmishes, but for the most part, this is a father and son story, so it's a rousing, underdog, kind of sports drama," Jackman continued. "It was nice to play that arc."
Jackman recently promoted the film with an appearance on "WWE's Monday Night Raw," where he punched a wrestler in the face.
In February, the actor said he was eating 6,000 calories a day to get back in character for an upcoming "Wolverine" film.
Jackman, 42, had undergone an intense diet to bulk up so he could play the beefy Marvel Comics mutant in the 2009 movie "X-Men Origins: Wolverine," an "X-Men" movie spin-off. The actor, who is about 6-feet-2-inches tall said he has restarted the plan, which consisted of consuming entire chickens.
At the premiere, Jackman told OnTheRedCarpet.com that he thought Wolverine would win in a fight against his "Real Steel" robot Adam, adding, "Come on, those claws are going to take him down!"
"Real Steel" hit theaters on October 7. Watch the trailer below.
