He eventually stood out in Robert Altman's MASH (1970) and made another memorable turn as Shirley MacLaine's husband in The Turning Point (1977), a role that led to parts in Ridley Scott's Alien (1979), David Cronenberg's The Dead Zone (1983) and Tony Scott's Top Gun (1986). The 1990s brought a plum role in A River Runs Through It (1992), an Emmy-winning run as a small-town sheriff in television's "Picket Fences" (1992-96) and another brush with aliens in Contact (1997).
Other work includes Tears of the Sun (2003) with Bruce Willis and Monica Bellucci, the television movie Vinegar Hill (2005) with Mary-Louise Parker and the miniseries "The Grid" (2004) with Dylan McDermott and Julianna Margulies.
