Jason Isaacs has revealed that he had to beat up Taylor Lautner in their new movie Abduction.
The pair star together in the John Singleton directed movie, which also stars Maria Bello and Sigourney Weaver.
And the actor admits that he was impressed by the physicality of the young actor.
Speaking to the Belfast Telegraph the actor said: "He is a martial arts wizard in real life - he can do standing double back somersaults, and he used to do exhibitions at the karate world championships - but I had to beat him up, and I couldn't beat my wife in a fight.
But the actor admits that he enjoyed working with the Twilight star and is now firmly on Team Jacob.
"It was interesting to see another young person who is universally known but very different to Daniel, Rupert and Emma. The Twilight phenomenon is different.
Jason added: "I am now - and have to be - Team Jacob, because Taylor is a lovely boy."
Isaacs is back on the big screen this week with his new movie Harry Potter and the Deathly Hallows - Part 1, which sees him reprise the role of Lucius Malfoy.
The second part of the final Potter instalment hits the big screen next year.
Harry Potter and the Deathly Hallows - Part 1 is out now.
