Peter, Jack, and Michael, 3 Men and a Little Lady
The wedding crashing scene in 3 Men and a Little Lady may be the most complex one we've come across. After Peter (Tom Selleck) realizes his feelings for Mary (Nancy Travis), he runs to the church to disrupt her wedding to a scheming Englishman. Despite his efforts, he is too late. But wait — it turns out the officiant was Jack (Ted Danson) in disguise the whole time! Thus, the wedding is null, and Mary is free to marry Peter instead. Crafty, those three men.
