On June 26, 2018, it was announced that Mark Wahlberg and Peter Berg would collaborate for the fifth time on the film adaptation of Wonderland, one of the novel series written by Ace Atkins based on the Robert B. Parker's character Spenser, which would be streamed by Netflix. The script, by Sean O'Keefe, is a very loose adaptation of the novel. The characters in the film do not reflect the characters in the novel beyond the names used. Nothing else about them is reflected in the novel or the original works by Robert B. Parker. 
The Film is to be produced by Neal H. Moritz through his Original Film along with Stephen Levinson and Wahlberg, and Berg through his Film 44. In October 2018, Winston Duke joined the cast to play Hawk. That same month, Post Malone, Alan Arkin, Iliza Shlesinger, Bokeem Woodbine James DuMont, Marc Maron and Michael Gaston joined the cast of the film. In November 2018, Colleen Camp joined the cast of the film.
Filming began in late 2018 in, Boston. The residence of character Cimoli (with whom Spenser is staying) was filmed in the Jones Hill neighborhood of Boston, on the street where actor Wahlberg lived during his teenage years.
