'The Wire' and 'Luther' star Idris Elba is to play Dr Alex Cross, the character Morgan Freeman played in 'Along Came a Spider' and 'Kiss the Girls'.

Deadline reports that Elba will star in 'Cross', an adaptation of author James Patterson's twelfth Alex Cross novel of the same name.

In the book Cross is hunting a serial killer who may be connected to the murder of the former FBI man's wife.

It is thought that production on the film will begin in the spring.
