Can you guess this movie trio?

I just wrote a review of “No Strings Attached” for Spokane Public Radio , which will run on Friday and Saturday. But I thought I would share part of it here:

“But the way a movie ends is important. It’s what you’re left with when you exit the theater. In the best cases, it makes up the enduring memory of what you’ve just experienced. It could be a snow sled going up in flames. It could be two outlaws frozen in a hail of gunfire. It could be a winded couple, one wearing a wedding dress, sitting in the back seat of a school bus, slowly realizing that they have no clue about what to do next”

I’m just curious. Who can identify the three movies that I refer to? It shouldn’t be that hard for a true cinephile.
