Thomas Lennon had a great time filming his debut episode for “Lethal Weapon” with the show’s lead stars, Damon Wayans and Clayne Crawford.

“Working with the two of those guys was an endless delight,” Lennon told Uproxx. “They’re so unbelievably funny, and also [have high] … level of dedication.”

Although Lennon only met Crawford on set, the “Odd Couple” actor revealed that they clicked immediately right after shooting their first scene together. “I didn’t really know Crawford very much beforehand, but the very first scene we shared together was fun,” Lennon said.

In a separate interview with TVLine, Lennon admitted that he actually mistook Crawford’s stunt double for the actor. “Clayne — I didn’t really know him, and on the very first day I went up and introduced myself to his stunt double,” the 46-year-old recalled. “Thinking his stunt double must have been the star of the show, I went up to the stunt double and said, ‘I’m such a big fan.’ Then when I walked another 20 feet farther and I realized, ‘Oh, no. This is much more the TV version of that guy. This must be Clayne.’ So we hit it off.”

Lennon made his debut appearance as Leo Getz in tonight’s Season 1, episode 15 of the FOX series. Getz, an ambulance-chasing attorney, was the key witness to a murder related to the drug cartel. He was used by Murtaugh (Wayans) and Riggs (Crawford) as bait to catch the group responsible for the killing.

Although Getz played a prominent role in the “Lethal Weapon” film series, viewers may not see Lennon’s version of the character on the TV show that much. “You know, there’s really no guarantee of that,” Lennon told Screener when asked if he’s returning for more episodes this season. But given the chance, he said that he would love to bring Getz back to the buddy cop series.

“It was one of the most fun shows I’ve been on in years, if not longer. Since doing my own show at least,” he told Uproxx. “[So] I would love to [come back]. … The only trick is the production schedule, which is basically a movie every nine days. Almost. It’s very intense.”

“Lethal Weapon’s” next episode (Season 1, episode 16) airs on Wednesday, Feb. 22 at 8 p.m. EST on FOX.
