Will Arnett seems to be taking his work home with him.

ET's Carly Steel caught up with The LEGO Batman Movie star at the animated film's premiere over the weekend, where he admitted that he sometimes leans on his superhero voice to help parent his two sons, Archie, 8, and Abel, 6.

"Just the kids when I'm trying to get them to turn off their iPads," Arnett said when asked who he uses his Batman voice for in real life. "It allows me to drop into the Batman voice when I need to drop the hammer at home."

While Arnett is getting his home in order, his animated alter-ego is trying to clean up an entire city.

In the movie, there are big changes brewing in Gotham. If Batman (voiced by Arnett) wants to save the city from The Joker (voiced by Zach Galifianakis), the caped crusader will have to ditch the lone wolf approach, and team up with some other vigilantes to defeat his archenemy.
