The Picasso Summer is a 1969 drama starring Albert Finney and Yvette Mimieux. The screenplay was written by Ray Bradbury (using the pseudonym of Douglas Spaulding) based upon his 1957 short story "In a Season of Calm Weather."

The original director was Serge Bourguignon, whose rough cut was rejected by Warner Bros. Another director, Robert Sallin, was hired to reshoot some scenes and the changed ending. Even with the reworked scenes, the film was never released to theaters in the United States. It was sold for distribution to television networks and stations with Sallin receiving credit as the director.

Future Academy Award winner Vilmos Zsigmond was the cinematographer.
