 In a documentary on the making of the film, director  Richard Donner (qv) recalled how he had written down the first  pieces of information he received regarding the film onto the back  of a business card. He held onto the card as a souvenir, and  displays it in the documentary "Taking Flight". Close examination of  this card reveals that, at one point, Nick Nolte (qv) was being  considered for a role in the film.
