For one, hes a giant man, Viswanathan tells EW of working opposite the former pro wrestler.

I felt so small and unfit!

Hes such a sweetheart and such a deep, really awesome guy.

We have something called the formal, but American prom is definitely different, she says.

I want a corsage!

I want a date!

So getting to actually have my own movie American prom was a real treat.

Acting with an American accent was simple enough with the exception of a certain restaurant name.

So that took a few takes.

Viswanathans other acting challenge?

Acting drunk when her character engages in some prom-night revelry.

My technique is just spin around in a circle on the spot right before they call action.

It works really well, says Viswanathan.

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.

Blockers, also starring Leslie Mann and Ike Barinholtz, hits theaters Friday.
