Glitch! is a 1988 American comedy film directed by Nico Mastorakis. It involves two petty thieves who accidentally become casting directors of a film with a large number of beautiful girls, and later they must dodge the Mafia.
Two thieves rob a large fancy house when the owner is away, but when a visitor mistakes them for the owner, and they find out about a casting party misscheduled for that day, they decide to stick around for fun. They have only one small problem, though. The real owners owe some bad dudes a lot of money, and they show up to collect it.
