Calvin Lockhart was a Bahamian–American stage and film actor. Lockhart was perhaps best known for his roles as Reverend Deke O'Malley in the 1970 film Cotton Comes to Harlem and Biggie Smalls in the 1975 Warner Bros. film Let's Do It Again.

Cotton Comes to Harlem is a 1970 American neo-noir action comedy film co-written and directed by Ossie Davis and starring Godfrey Cambridge, Raymond St. Jacques, and Redd Foxx. The film, later cited as an early example of the blaxploitation genre, is based on Chester Himes' novel of the same title. The opening theme, "Ain't Now But It's Gonna Be," was written by Ossie Davis and performed by Melba Moore. The film was one of the many black films that appeared in the 1970s and became overnight hits. It was followed two years later by the sequel Come Back, Charleston Blue.
