According to Jerry Schatzberg, Gene Hackman was hard to work with and argued with everyone on the set including his brother, Richard Hackman, who was working as his stand-in. To get back at Gene, Schatzberg gave Richard a part in the film. But Gene ended up being delighted that his brother was in the film.
Gene Hackman was asked in a rare interview about his favorite movie of all the ones he did , He said its really hard to pick its just like picking one of your children , However he said " ...there was a movie i did years ago , didnt get much press , it was called Scarecrow."
The film was entered and selected to screen in competition at the Cannes Film Festival in 1973 where the picture won in a tie the prestigious Palme d'Or (The Golden Palm) award shared with Alan Bridges' The Hireling (1973).
Near the end of 'Blazing Saddles (1974)' when Cleavon Little is riding his horse as he is escaping out of the front gate of the Warner Brothers lot, you can see the poster for this film in the top right hand side of the screen, above the "Martino's" delivery truck, on the wall of the studio.
When Max and Lion go into the diner to have breakfast early in the film, the song playing on the jukebox is the top 40 hit "Silver Moon" sung by former Monkee Michael Nesmith, then with the First National Band.
