The random fly in Raiders of the Lost Ark
As you already know, some things don’t exactly go as planned. The wind might pick up, the actors can forget their lines, or an annoying fly can try to make a cameo in a huge blockbuster hit. That’s what took place while shooting Raider of the Lost Ark.
When Indiana Jones is about to shoot a rocket launcher (all archeologists have one), Dr. René Belloq (Paul Freeman) talks about how Indiana’s persistence surprises him while eating a fly in the process. The fly flew onto Paul’s mouth, and we never see it fly away. The production team could have edited it out of the movie, but they decided to leave it alone. Gross.
