Good news! We don't have to wait until Batman v Superman: Dawn of Justice is released in 2016 to hear Ben Affleck utter the iconic "I'm Batman" catchphrase.

Affleck busted out the famous line while goofing around with Seth Lee, a young actor that is co-starring in The Accountant with the 42-year-old film star. He says the line twice, but it is his first attempt that is probably the closest to what we'll hear in Zack Snyder's superhero film.

Check it out in the video below.

Fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s most revered, modern-day savior, while the world wrestles with what sort of hero it really needs. And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it’s ever known before.

Zack Snyder's Batman v Superman: Dawn of Justice is in theaters March 25, 2016.
