Watching Ill Met By Moonlight again tonight, and just having read Phylida Houseman's recollections of the making of the film, something came to me... In the film, the S.O.E. British Liaison Officer Johnny Houseman who's part of the party on Crete that welcomes Billy Moss to the island is played by her husband...Johnny Houseman! 8O 8O 8O (She herself later appears briefly as "Mihali's sister" in the glendi scene) Yes, an ACTUAL S.O.E. BLO present during events in 1944 played HIMSELF!!! The production was actually quite a reunion; Xan Fielding, Senior BLO for a time and author of "The Stronghold" and "Hide And Seek" about his time on Crete was a technical adviser, as was Mickey Akoumianakis...and later in the filming Paddy Fermor turned up for a couple of days! Are there any other instances in the cinema or television of this happening??? And NOT in a documentary appearance... I know Richard Todd came close - he was originally approached to play himself in The Longest Day but refused, and instead played Johnny Frost.
