Over the course of filming, the budget ballooned from $8 million to $11 million (big money back then, especially for a film the studio didn't think could earn it back). Props malfunctioned, costumes malfunctioned, wardrobe malfunctioned (with those last two words did you just picture C-3PO's chest plate opening and a boob popping out? Because we did).
And just in case you weren't picturing it...
How cursed was this production? At one point a freak rainstorm in Tunisia delayed the filming of the Tatooine scenes, which as you may recall were all in the desert. You read that right: freak rainstorms. In the desert.
As they were finishing filming, Mark Hamill got into a car accident, smashing his face (he was supposedly in surgery for seven hours to put the bones back together).
So it wasn't just the cast and crew, God apparently hated Star Wars too.
