|Rock Hudson (1925 - 1985)|
|Winchester '73 (1950) [Young Bull]: Shot in the chest by James Stewart as Rock and his warriors charge towards the Cavalry. (Thanks to Gordon)
Seconds (1966) [Antiochus 'Tony' Wilson]: Killed (off-screen) by the doctors of the mysterious 'rejuvenation' company; the movie ends with Rock being wheeled into the operating room after being given last rites. (Thanks to Mac)
Pretty Maids All in a Row (1971) [Michael 'Tiger' McGrew]: Possibly commits suicide by driving his car off of a pier and drowning himself; it's implied that he may have actually faked his death and fled the country, but I'll list this just in case.
