I saw a movie in the late 1980s or early 1990s. The main characters were a small group of men who were con artists (I think) with at least one of them involved with stage magic or movie special effects.

They need to trick the antagonist — something to do with a Very Important Folder of Papers. So, naturally, they make him think he’s been kidnapped by aliens. No idea why.

So, they show him a guy “floating” using his stage tricks, show him some people dressed as aliens, and put him inside a fake UFO and successfully trick him into thinking it’s all real.

They have the UFO on the back of a truck and drive it down the highway under a tarp to make him think it’s moving. At one point they get pulled over by a cop and almost exposed.

Searching for “fake UFO,” “fake aliens,” “con artists + aliens” etc. has led to some very strange links, including a video of someone who claimed to see a REAL flying saucer on the back of a truck on the highway.

Anyone know what movie this is?

Thank you!
