|Danny DeVito (1944 - )
Mr. Rhea Perlman
|Johnny Dangerously (1984) [Burr]: Trampled to death (off-screen) after a bull crashes through the wall of the bar (in a parody of the then-current Schlitz Malt Liquor ads). We see him screaming as the bull charges towards him, followed by a newspaper headline reading "D.A. Dies in Commercial." (Played for comic effect, obviously.)
Head Office (1985) [Frank Stedman]: Commits suicide by jumping out of the window in an office building. (Played for comic effect.) (Thanks to Neil)
Batman Returns (1992) [Oswald Cobblepot a.k.a. The Penguin]: Fatally injured when he falls through a skylight and into the water below, he emerges from the water and approaches Michael Keaton menacingly before he finally collapses and dies.
Hoffa (1992) [Bobby Ciaro]: Shot to death by Frank Whaley when Danny tries to save Jack Nicholson. (Thanks to Fred)
Mars Attacks! (1996) [Rude Gambler]: Disintegrated with a ray-gun by a Martian in a junkyard.
L.A. Confidential (1997) [Sid Hudgens]: Beaten to death (off-screen) in his office by James Cromwell. His body is shown afterwards when Russell Crowe and Guy Pearce investigate the scene.
Heist (2001) [Mickey Bergman]: Shot to death by Gene Hackman. (Thanks to Gary)
Death to Smoochy (2002) [Burke Bennett]: Although he survives the actual movie, the US DVD includes a deleted scene in which Danny and Jon Stewart are shot to death (off-camera) by Pam Ferris and her men; we hear the shots as Catherine Keener and Edward Norton walk out of the building. (Thanks to Tommy)
Nobel Son (2007) [Gastner]: Electrocuted with a radio (off-screen) in the bathtub; his body is shown afterwards when Bryan Greenberg and Mary Steenburgen discover him. (I'm unsure whether it was suicide or whether he was killed by Shawn Hatosy.)
