Crazy ex-boyfriends, paranoid fathers, and a missing groom—these are just some of the staples of awesome Hollywood onscreen weddings. And even though those "happily ever afters" sometimes don't work out, movie audiences still love watching a good film wedding and being inspired by the perfect (or charmingly not-so-perfect) ceremony.

And what if you and your guy are planning to tie the knot yourselves? Even though you might not be that enthusiastic about bachelorette parties or an overeager mother-of-the-bride scenario, you have to admit that movie weddings can give you great ideas about your own wedding, as well as lessons on what to do and what to avoid. After all, June’s one of the most popular months to get married in, and what better way to see whether or not a wedding works than on the big screen?

Check out our list of 20 memorable movie wedding scenes in the gallery below.
