Billy = Adam DeVine (I low key think his persona is influenced by Billy, Adam Demamp seems drawn from him too, and they all share a derpy physicality I would say)
Mandy = Aubrey Plaza? Doesnt “look” like Mandy at first but April from Parks and Rec seems very Mandy
I was gonna say Seth Rogan for Billy, but seeing you suggest Adam Devine I have to agree. He has the same goofy dumb guy energy but also kinda looks like Billy already.
Aubrey Plaza would make a great Mandy, too. Trying hard to think of another actress that can do the monotonous idgaf attitude as well and I’m coming up blank.
