Josh Gad has joined the all-star cast of Fox's adaptation of Agatha Christie’s Murder on the Orient Express, The Hollywood Reporter reveals.

Kenneth Branagh is leading a whole carload of boldface names such as Johnny Depp, Michelle Pfeiffer, Daisy Ridley, Michael Pena and Judi Dench. Branagh is also directing.

The story centers on a murder onboard the famous train and introduces Belgian detective Hercule Poirot (Branagh), who must solve the case while being surrounded by duplicitous passengers.

Gad will play Hector McQueen, a skittish man who drinks too much and works as an assistant/translator to Depp's character.

Gad, who may be best known as the voice of Olaf in Frozen, will be seen in Disney's live-action take on Beauty and the Beast and is doing the voice of the canine in DreamWorks’ A Dog’s Purpose. He also originated one of the two lead roles on Broadway’s The Book of Mormon.
