There was an end of the world movie where a pregnant women is trying to get home, another man has sex with anyone who moves, some people are going to this massive concert. Everyone knows the world is going to end. The movie ends with two people on a roof. I am going crazy trying to remember the title of this movie. I would appreciate any help I can get. Thanks.

Last Night

Go to the Internet Movie Database, The Internet Movie Database (IMDb). It contains a large database covering movies and TV shows of all varieties, and its search engine facilitates any number of approaches to deciphering a movie's title.

Click on the "Characters" option in the search window, then write the name of the character. This will take you to the character's home page, which ideally will have the name of the film itself. If the character appeared in more than one film (Sherlock Holmes, for example), there may be more than one movie listed. In some cases, there won't be a listing for the character, in which case you should return to the IMDB home page and start again.

Click on the "Names" option in the search window, then type in the name of the actor or director. You'll be sent to a page containing a list of all his work. Scroll through it until you find the name of the film you're looking for. This may take a little more work, but if you pinpoint the film name, you can be more assured that it's the right one. If you can't find it, go back to the IMDB home page.

It might be that one movie called last night or something like that
