Assassinio sul Nilo

Many of the characters are combinations or alterations of characters from the novel, to make for a smaller cast and a less confusing plot:

• Salome and Rosalie Otterbourne, a romance novelist and her daughter, become a singer and her niece/manager.
• Andrew Pennington becomes cousin Andrew Katchadourian.
• Marie Van Schuyler, a socialite and no relation to Linnet, becomes Linnet's godmother who has the ideals of Mr. Ferguson, the aristocrat turned socialist.
• Windlesham, a character mentioned in the first chapter, is combined with Dr. Bessner to become Dr./Lord Windlesham.
• Bouc, a character who appears only in Murder on the Orient Express, takes on elements of Col. Race, while his choice of traveling companion, his mother Euphemia, is reminiscent of the relationship between Tim and Mrs. Allerton.

Poirot grows a mustache to hide the scar tissue that covers most of his upper lip and cheek. Scar tissue cannot grow hair at all, as it does not contain follicles or sweat glands; it is a connective tissue that grows between the dermis after it is split. Poirot's mustache could therefore never be as full as depicted, and should have several holes or irregularities.
