Mike and Dave Need Wedding Dates (2016)

Continuity mistake: At the end of the movie, when Alice grabs Dave and starts kissing him on the bench, she doesn't have any shoes on. A second later, in the next shot, she has flip flops on. Then the shot changes again and she is once again barefoot, without any shoes on. (01:29:40)

Continuity mistake: When Mike draws the line in the sand, a woman walks up in close proximity behind Dave. In subsequent shots in the same scene, she is gone, although there was not nearly enough time for her to move out of view in any direction.

Other mistake: Mike and Dave put the ad on Craigslist, and people begin to share it through social media. The first time we see someone share it through Facebook the date of the post is "March 19 at 12:38 AM." Moments later there's a zoom in and now the date is still the 19th, still at 12:38 AM, but the month changed to May. (00:12:30)

Dave Stangle: Maybe Dad'll just forget about his ultimatum.
Mike Stangle: Why would Dad forget about an old tomato?
Dave Stangle: No, his ul... his ultimatum.
Mike Stangle: Old tom...?
Dave Stangle: Ultimatum.
Mike Stangle: Are you saying "old tomato"?
Dave Stangle: Ultima-tum, like a tomb or a crypt.

Burt Stangle: I want you two to bring a date. That's two dates.
Dave Stangle: You want us to bring dates to a wedding?

Dave Stangle: Are you allowed to do that?

Tatiana: One time I got high, I read the back of the shampoo bottle for thirteen hours.
Jeanie Stangle: Because it said repeat.

Jeanie Stangle: I get it.
