Daniel Radcliffe is the latest star to join the cast of Paramount’s “The Lost City of D,” taking on a villainous role in the romantic adventure.

Sandra Bullock and Channing Tatum star in the film, which follows a reclusive romance novelist (Bullock), who was sure nothing could be worse than getting stuck on a book tour with her cover model (Tatum), until a kidnapping attempt sweeps them both into a cutthroat jungle adventure, proving life can be so much stranger, and more romantic, than any of her paperback fictions.

Though Radcliffe is best known for playing the ultimate hero Harry Potter, this is not the actor’s first foray into the dark side; Radcliffe has played the bad guy in movies like “Now You See Me 2.”

Radcliffe currently stars in TBS’ “Miracle Workers,” which is heading into its third season. He also recently starred in “Swiss Army Man,” “Guns Akimbo” and last year’s “The Unbreakable Kimmy Schmidt: Kimmy vs. the Reverend.”

Adam and Aaron Nee are directing from a script by Dana Fox. Bullock is also producing through her Fortis Films banner, with Liza Chasin’s 3dot Productions. Seth Gordon is attached to produce via Exhibit A.

Last week, Variety exclusively reported that Patti Harrison would join the cast (details of her role are being kept under wraps). “Dolemite Is My Name,” “High Fidelity” and “The United States vs. Billie Holiday” breakout Da’Vine Joy Randolph also stars.

Radcliffe is repped by ARG and Felker Toczek Suddleson Abramson.

Deadline was first to report the news of Radcliffe’s casting.
