Graham Stevens played the board game Clue as a child and saw the movie adaptation when it came out in 1985.

In no way could he have imagined that 40 years later he’d be playing Professor Plum, one of the mansion-trapped characters/suspects in “Clue: On Stage,” a theatrical adaptation of the whodunit.

“I had to beg my parents to take me to the movie,” Stevens, who was born in Detroit, says, adding that its three different endings presented something of a challenge for fans. “You had to go to three different (showings) in order to see them all. I managed to get them to take me to one, but I couldn’t save up enough allowance to get to all of them.”

“Clue: On Stage” only has one ending — which Stevens, 48, won’t give away. But in his third go-round in the show, he maintains that the real fun is in the story and not the solution.

“It’s really a fast-paced, sort of slapstick comedy,” says Stevens, who’s played Professor Plum and Mr. Boddy in previous productions. “There’s lots of sort of crackling dialogue and tons of laughs. It’s an ensemble piece, and so each actor has a really funny punch line or comedy bits.

“When the audience really gets going and laughing, it’s really fun to keep that energy going. It’s just a blast if you enjoy performing comedy, and I do.”

Stevens’ path to the stage began in San Diego, where his family moved when he was young. “Detroit for me was more of a distant home,” Stevens said, “but I’ve always treated it as a kind of home, especially when I was a kid and (the Detroit Tigers) won the World Series in 1984. I was the only Tigers fan in my entire elementary school” — when the team defeated San Diego’s Padres in five games.

Stevens, whose parents are Detroit natives, still has an aunt and uncle in Royal Oak and other relatives around the state. He performed in Detroit as part of “Beetlejuice” in 2023 at the Detroit Opera House.

With parents who worked in the entertainment industry — dad was a cameraman and live TV director, mom was an improv actor — Stevens developed an interest in the arts early. As a child, he spent time on the set of a show his father worked on called “Tin Pipes,” and he became a fan of television and movie comedies, especially “Monty Python’s Flying Circus.”

He began acting during high school, including with a local professional comic opera company. He then studied at Yale, majoring in theater and becoming active in the Yale Dramatic Association (aka Yale Dramat). “That’s a great place for students to do theater,” Stevens says. “You get a lot of opportunities, not just with the Dramat, but outside, as well.” It set him up for a move to New York after graduation, where he got his Equity card with Theater Works USA and later created the role of Nate in the Off-Broadway production of the musical “In Transit,” which won a Drama Desk Award for Outstanding Ensemble.

“That was so much fun — so much fun,” Stevens says. “‘In Transit’ was one of those shows where the actors are doing literally everything — the singers were the band, a lot of times we were moving set pieces around ourselves. It was a real challenge on all fronts, but a real fun one.” He also spent time in Broadway productions of “Beetlejuice” and “Monty Python’s Spamalot,” the latter a particular favorite, not surprisingly.

“I definitely used my extensive Monty Python fandom in that one,” recalls Stevens, who played King Arthur.

Stevens will be with “Clue” through the tour’s conclusion during the spring and has “some things on multiple burners” for the future. He’s confident that mystery will have a satisfactory conclusion as well, however.

“I’ve been in show business now for just over 30 years,” he says, “ever since those first shows I did in high school. Honestly, it’s been immensely rewarding. It can be tough at times. You don’t always get the parts you want. But I’ve always been really lucky to work with really good people on really great projects. So overall, it’s been a really rewarding time.”

“Clue: On Stage” runs Tuesday, Feb. 4 through Feb. 9 at the Fisher Theatre, 3011 W. Grand Blvd., Detroit. 313-872-100 or broadwayindetroit.com.
