Thugs With Dirty Mugs is a 1939 Warner Bros. cartoon in the Merrie Melodies series.
Its subject matter (movie gangsters) is a parody of Warner's famous cycle of crime films starring such actors as James Cagney, Humphrey Bogart, George Raft, and Edward G. Robinson. The title derives from the studio's 1938 acclaimed feature film, Angels with Dirty Faces, which starred the first two. It is similar to Avery's later MGM crime/detective-oriented cartoon, Who Killed Who?.
