It's considered cheesy for a character to name drop the title of the film by today's standards, but back in the day the “title drop” was something viewers anticipated, cheered at and talked about after watching a movie.
Some movies like Good Morning Vietnam, White Men Can't Jump, Dude, Where's My Car?, Stop! Or My Mom Will Shoot and What About Bob? Use the title drop during a memorable scene.
Others like The Godfather, The Big Lebowski, Hobo With A Shotgun, The Wolf Of Wall Street and Fantastic Mr. Fox are named after the main character so the name drop feels natural but doesn't make for a quotable moment.
All of these movies also have one other thing in common- they're all included in this compilation video by Roman Holiday entitled “Title Drops” along with around a hundred and forty more.
