According to The Hollywood Reporter, Derulo, best known for platinum singles such as "Wiggle", "Talk Dirty", "In My Head", and "Whatcha Say", will play a feline named Rum Tum Tugger, who is rebellious and never satisfied.
The film will be directed by Oscar-winning filmmaker Tom Hooper and shooting is expected to start soon in England.
The story follows a tribe of cats called the Jellicles and the night they make what is known as "the Jellicle choice" and decide which cat will ascend to the Heaviside Layer and come back to a new life.
Hudson, who won an Oscar in 2007 for her role in Dreamgirls, will take on the role of Grizabella, a former glamour cat ostracised by the Jellicles, while McKellan will play Old Deuteronomy, the elderly Jellicle Leader.
Elba will be portraying Macavity, the villain of the piece. Dench will essay the role of the Old Deuteronomy, the Jellicle leader who is kidnapped by Macavity.
The stage version of the musical is the fourth-longest-running show in Broadway history and the sixth-longest-running in London's West End.
