Adam Wingard released another movie last year called
The Guest. If you enjoyed
You're Next, you'll probably like this one. It's more of a thriller/action movie but it still has the light touches of humor and fun throughout. I think he has another movie in the works but it's slipping my mind as to what it is.
EDIT: It's
The Woods--Involve a group of college students on a camping trip who discover they are not alone.
It's going to come out this year. I remember seeing the trailer and it looks...interesting? But most of his films have trailers that are cut to make his stuff look more generic so...
