Brad Pitt will have a cameo in Sandra Bullock's new romantic-action-adventure-comedy Lost City of D. According to The Hollywood Reporter, this is a "friendly quid pro quo," as Bullock is signed on to have a cameo in Pitt's Bullet Train, and now he's returning the favor.

　　"Bullock, who is producing as well as starring in [Lost City of D], saw an opportunity for a fun casting, she reached out to her pal, who said yes," according to THR.

　　The Lost City of D follows a romance novelist (Bullock) who is on a book tour with her cover model (Channing Tatum) and they get kidnapped and taken into the jungle. Throughout the course of the film, Bullock learns that "life can be so much stranger, and more romantic, than any of her paperback fictions."

　　Filming is expected to take place this summer in the Dominican Republic. Patti Harrison (I Think You Should Leave) and Da'Vine Joy Randolph (Office Christmas Party) are also set to appear in the film, which will be directed by Adam and Aaron Nee (Band of Robbers, The Last Romantic).

　　Daniel Radcliffe, meanwhile, is lined up to play the villain in Lost City of D.
