In terms of casting and production itself, Spielberg has a known penchant for working with actors and production members from his previous films. For instance, he has cast Richard Dreyfuss in several films: Jaws, Close Encounters of the Third Kind, and Always. Aside from his role as Indiana Jones, Spielberg also cast Harrison Ford as a headteacher in E.T. the Extra-Terrestrial (though the scene was ultimately cut). Although Spielberg directed veteran voice actor Frank Welker only once (in Raiders of the Lost Ark, for which he voiced many of the animals), Welker has lent his voice in a number of productions Spielberg has executive produced from Gremlins to its sequel Gremlins 2: The New Batch, as well as The Land Before Time, Who Framed Roger Rabbit, and television shows such as Tiny Toons, Animaniacs, and SeaQuest DSV. Spielberg has used Tom Hanks on several occasions and has cast him in Saving Private Ryan, Catch Me If You Can, The Terminal, and Bridge of Spies. Spielberg has collaborated with Tom Cruise twice on Minority Report and War of the Worlds, and cast Shia LaBeouf in five films: Transformers, Eagle Eye, Indiana Jones and the Kingdom of the Crystal Skull, Transformers: Revenge of the Fallen, and Transformers: Dark of the Moon.
