Meanwhile, his big screen reputation grew with critically acclaimed work in such comedies as "The Landlord" (1970) ”The Skin Game”(1971) with James Garner, "Travels with My Aunt" (1972) and the film adaptation of the Tony Award-winning drama "The River Niger" (1975). A riveting performance as a drug-dealing cutthroat stalking Nick Nolte and Jacqueline Bisset in "The Deep" (1977) catapulted him to wider popularity, but the tough by-the-book drill sergeant in "An Officer and a Gentleman" (1982) won him a Best Supporting Oscar that consolidated his place in the Hollywood hierarchy.

 Following his Oscar, he made numerous big screen and television appearances ,being singled out for his work as Egyptian president Anwar Sadat in “Sadat”(1983), the sci-fi adventure "Enemy Mine" (1985) where his lizard-like makeup won kudos, and in the action adventure series "Iron Eagle" (1985,1986,1992,1995) which introduced him to a whole new generation of moviegoers.

Still going strong, Lou’s trendsetting bald head and imposing six-foot-four physique served him well in "Diggstown" (1991) where he played a down-and-out boxer, a heroic headmaster in “Toy Soldiers” (1991).

Lou's well thought out and nuanced performances also managed to give credibility to socially themed projects such as “To Dance with Olivia” (1997), and the critically acclaimed “Jasper, Texas” (2003)

The recipient of every known acting accolade, including multiple Golden Globes, Emmys, and People’s Choice Awards, Lou’s performance has connected him with his fans on a global scale.  Organizations such as the NAACP, CARE, and the United States Armed Forces have used his likeness to add validity and integrity to their causes.

 Currently, Lou has become the new lead on the popular science fiction series “Stargate SG-1” introducing him to a new generation of fans worldwide.  Lou is also developing a nonprofit foundation aimed at creating entertainment that helps bring awareness and education to issues such as racism, ignorance, and societal apathy.
