Harrison Ford and Steven Spielberg clashed with George Lucas over "Indiana Jones and the Kingdom of the Crystal Skull."
"They didnโt want to do a โRaidersโ movie that involved aliens, and they kind of got into a fight with George about it," producer Kathleen Kennedy recalls. "They were not 100 percent on board, which is why the movie, out of the four that Steven made, is the weakest."
George Lucas adds: โI wanted it to be kind of a โWar of the Worldsโ sort of thing. Harrison said, โIโm not going to do another science-fiction movie.โ And Steven said, โIโm not going to do another science-fiction movie.โ I said, โSteven, this is perfect because itโs the 1950s, when flying saucers were a whole thing,โ but he said โno.โ We did about five scripts, and finally Steve and I compromised: โLook, what if theyโre not aliens but from another dimension.'โ (via Vulture)
