So I vaguely remember watching a movie a few years back. I remember bits and pieces that I'm hoping will lead me to the results.
The movie has a scene where there are a bunch of people on a rooftop waiting for? Possibly aliens or something to happen, they are all holding signs.
A little later one of the characters goes to a friends house who is having as much sex with as many different women as he can before? Possibly the world ending, and I do remember that when the character walks in he passes a woman and questions his friend if that was there teacher from school, I believe he than borrows his friends muscle car? Possibly a purple challenger and than I left and didn't catch the rest, anybody out there please help, it's been bugging me for too long
