Munoz began in the entertainment industry in the 1980s when he managed the alternative Gospel band, Level Heads, featuring Juno award-winning musician, Jim Chevalier.

In 1988, Munoz went on to promote Freedom 88, a three-day alternative Gospel Music festival at Bingeman Park in Kitchener, Ontario with such notable names as Steve Taylor, Adam Again, and the Grammy-award-winning band The Choir.

In the 1990s, he turned to musical theatre, collaborating with sons Miq and Mann Munoz on Job and the Snake, which premiered in the Niagara Peninsula in September 1994.

[2] The musical featured Lee Siegel in the role of Job, who has since gone on to perform in the Broadway revival of Jesus Christ Superstar.

[9] In 2006, Munoz switched gears once again—this time to independent filmmaking—when he wrote, produced, and directed his first feature film, Dear J (originally entitled Liars and Lunatics[citation needed]).

The film features Joseph Halsey, Allison Lane, Carson Grant, and Karen Lynn Gorney in the role of the Judge.

Directed by Mann Munoz, it stars Jeff Stewart and Christopher Elliott, and also features Ken Jennings.

This film is based on the experiences of his maternal great-grandfather, who was one of the Germans from Russia who survived the Holodomor and was arrested and thrown into prison during Stalin's Great Terror in the late 1930s.
