No word on what role Malone is playing, but the movie is an adaptation of the novel "Robert B. Parker's Wonderland," written by Ace Atkins. The crime drama follows an ex-felon named Spenser (Wahlberg) returning to Boston's criminal underworld to unravel a twisted murder conspiracy. It's one of many adventures for Spenser, who has been the protagonist in dozens of detective novels that have all been New York Times bestsellers.
Malone joins co-stars Winston Duke, Alan Arkin, Iliza Shlesinger, Bookem Woodbine, Hope Wilson and James DuMont.
Malone is best known for hit singles "Rockstar" and "Psycho."
