A former professional prizefighter, Robert Kent entered films after gaining experience on the legitimate stage. His career consisted mostly of playing leads in "B" pictures. His "biggest" picture was probably Une fille de la province (1954), in which he was billed eighth, but he specialized in westerns, action/adventure films and serials, appearing in such pictures as Gang Bullets (1938), The Phantom Creeps (1939) and Twilight on the Trail (1941).
