Howard Hawks was one of America's greatest directors, and Scarface was one of his greatest achivements. Paul Muni and George Raft give great performances, but the real star of the film is it's director. His movement of the camera during the shootouts is masterlyand the film's scope never makes it overblown.

Some of Hawks' ather films are,

Red River(an absolute must-see)
Bringing Up Baby
His Girl Friday
El Dorado
