O Dreamland is a 1953 documentary short film by British film director Lindsay Anderson. The documentary was made in 1953 by Anderson and his cameraman/assistant, John Fletcher, using a single 16mm camera and an audiotape recorder. Once completed, the film was initially shelved, with Anderson commenting, "you don't do anything with a 10-minute, 16-millimetre film. It's just there, that's all." In 1956 however, he was inspired to include it as part of the first Free Cinema programme.
