Burr appeared in more than 50 feature films between 1946 and 1957, creating an array of villains that established him as an icon of film noir. Film historian Alain Silver concluded that Burr's most significant work in the genre is in these ten films: Desperate (1947), Sleep, My Love (1948), Raw Deal (1948), Pitfall (1948), Abandoned (1949), Red Light (1950), M (1951), His Kind of Woman (1951), The Blue Gardenia (1953) and Crime of Passion (1957). Silver described Burr's private detective in Pitfall as "both reprehensible and pathetic", a characterization also cited by film historian Richard Schickel as a prototype of film noir, in contrast with the appealing television characters for which Burr later became famous.  "He tried to make you see the psychosis below the surface, even when the parts weren't huge," said film historian James Ursini. "He was able to bring such complexity and different levels to those characters, and create sympathy for his characters even though they were doing reprehensible things."  Other titles in Burr's film noir legacy include Walk a Crooked Mile (1948), Borderline (1950), Unmasked (1950), The Whip Hand (1951), FBI Girl (1951), Meet Danny Wilson (1952), Rear Window (1954), They Were So Young (1954), A Cry in the Night (1956) and Affair in Havana (1957). Beyond noir, Burr's villains were also seen in Westerns, period dramas, horror films and adventure films.  "I was just a fat heavy," Burr told journalist James Bawden. "I split the heavy parts with Bill Conrad. We were both in our twenties playing much older men. I never got the girl but I once got the gorilla in a 3-D picture called Gorilla at Large. I menaced Claudette Colbert, Lizabeth Scott, Paulette Goddard, Anne Baxter, Barbara Stanwyck. Those girls would take one look at me and scream and can you blame them? I was drowned, beaten, stabbed and all for my art. But I knew I was horribly overweight. I lacked any kind of self esteem. At 25 I was playing the fathers of people older than me."  Burr's occasional roles on the right side of the law include the aggressive prosecutor in A Place in the Sun (1951). His courtroom performance in that film made an impression on Gail Patrick and her husband Cornwell Jackson, who had Burr in mind when they began casting the role of Los Angeles district attorney Hamilton Burger in the CBS-TV series Perry Mason.
