[WATCH] Ben Affleck Ruins “Let It Go” From ‘Frozen’ On ‘Tonight Show Starring Jimmy Fallon’: ‘Batman v Superman’ Star’s Son Isn’t Impressed By His Skills

You might think if you're a father playing Batman in the upcoming film Batman v Superman: Dawn of Justice your son would believe there's no cooler thing in the world. But apparently Ben Affleck's young child, Samuel, is more interested in something else... Jimmy Fallon's rendition of "Let It Go" from the uber successful Disney film Frozen.

Affleck dropped by Fallon's Tonight Show last night to promote his newest film, the David Fincher-directed Gone Girl, and during his segment he showed the world just why his son prefers the Tonight Show host's voice over his.

Yes, it's true: Ben Affleck doesn't have the greatest voice around, BUT he is a killer director and a very fine actor –– so let's give him a break, shall we?

Joking just after sitting in the guest chair, the Argo star and director admitted that his kids watch Fallon's program in "a very perverse way."

"If I was doing the sequel to Frozen, I'd be a hero!" he joked. So, in order to not have to sit through the movie again, Affleck began showing his son the Jimmy Fallon-Idina Menzel version of the song. Apparently little Samuel loved it, but it didn't work in Affleck's favor. Check out the actor's Tonight Show segment below:

So, is Affleck's son right? Is Jimmy Fallon the man, or is "pop-pop" the man? Remember ... be kind!
