Branagh boarded the film in June last year, aiming to direct and star as Agatha Christie's Hercule Poirot in the carriage-bound mystery. The book was first published in 1934, and sees Poirot exercising the little grey cells over the murder of an American tycoon on a journey from Istanbul (Constantinople at the time) to Paris.
Variety's report doesn't include what role Odom Jr. might be taking aim at, but if he does sign on, he'll be the second confirmed cast member after Branagh, as Angelina Jolie considered taking part, but never officially committed.
The story was famously adapted in 1974 by Sidney Lumet for a star-studded version that was nominated for six Oscars and won one for Ingrid Bergman. So, you know... no pressure. With Michael Green writing the latest script, Branagh is looking to have this one out next year.
