Jonah Hill has signed up for 'Django Unchained'.

The '21 Jump Street' star previously turned down a role in the spaghetti western movie - which will be directed by Quentin Tarantino - due to scheduling conflicts but he is now able to play a different character, who is as yet unknown, in the film.

Jonah rejected the role of Scotty Harmony, who loses the titular character Django's (Jamie Foxx) slave wife Broomhilda (Kerry Washington) to evil plantation owner Calvin Candie - who is played by Leonardo Dicaprio - which results in him being involved in a showdown with the slave-turned-bounty hunter.

The drama film focuses on Django's quest to recover his wife from Calvin - who runs club Candyland, where his spouse and other female slaves are exploited as sex objects - and Samuel L. Jackson, Christoph Waltz and James Russo have also signed up for the motion picture.

Jonah and Leonardo will then join forces for Martin Scorsese's 'The Wolf of Wall Street', which is based on Jordan Belfort's memoir of his rise and fall as a stockbroker.

John Dujardin has also been in talks to star in the crime drama, which will see Leonardo play Jordan, a multi Millionaire stockbroker who was charged with security fraud and money laundering, and served a 22-month prison stretch.
