Ishtar is a 1987 American adventure comedy film written and directed by Elaine May, and produced by Warren Beatty, who co-stars opposite Dustin Hoffman. The story revolves around Chuck Clarke and Lyle Rogers, a duo of talentless American songwriters who travel to a booking in Morocco and stumble into a four-party Cold War standoff.

The movie has a couple good bits, it’s only real crime is being a little boring. It’s definitely overblown in it’s legend of being bad, Biodome for instance made me viscerally angry in a way this movie never could.
