Steve Martin and Diane Keaton to star in One Big Happy

Steve Martin and Diane Keaton are attached to star in Paramount Pictures’ upcoming “One Big Happy” – which the studio picked up from a comic pitch by “Party of Five” creators Chris Keyser and Amy Lippman.

Variety reports the film’s details are being kept under wraps, but the plot reportedly follows a family having to reconnect and overcome various obstacles. It is produced by John Goldwyn and Lorne Michaels.

Martin and Keaton have already proven they have the chemistry to pull-off a married couple with their successful turns in Father of the Bride and its sequel.
