It’s hard to think about Robert Duvall and not remember the „I love the smell of napalm in the morning“ sequence. A second thought may evoke the conseglieri, a bald thx1138 and so on (depending on your movie expertise/nerdness degree)
But the point here is: must be hard for an actor to live his whole life/career associated with a one-liner. Even if it’s a fuckin' good one.
Some try to overcome the fact by killing wives, hidding in the mountains, joining the mexican soap operas.
Others put on a mustache.
