We have something called the formal, but American prom is definitely different, she says.
I want a corsage!
I want a date!

Viswanathans other acting challenge?
Acting drunk when her character engages in some prom-night revelry.

It definitely sells that youre drunk.
And then if you give a shot to walk, man, youre just wobbling all over the place!
Give it a go, for sure.
