It's a fact!

The late Clive Exton wrote a number screenplays for British television, perhaps most memorable being the Jeeves and Wooster dramatizations, as well some of the Poiroit adventures.

The late George MacDonald Fraser wrote the excellent Flashman series of novels, as well as a variety of lively historical pieces.

Together, they wrote Red Sonja.

Sadly, this combination of talents was not a "You got chocolate in my peanut butter!" situation.
