Scottish-born Graham McTavish’s acting resume covers just about every TV genre — just don’t look for him in a procedural.

“I’ve been very fortunate in the last few years to get into ‘The Hobbit’ [movies],” says McTavish, 58. “Do that for two-and-a-half years, immediately overlap that with ‘Outlander’ for two years and immediately overlap that with ‘Preacher’ and ‘Lucifer.’

“It’s genre geek heaven — not a lot of procedural police dramas in there,” he says. “No lawyers!”

If there’s a high-profile genre project — whether it be on TV or in the movies (“Aquaman”) — chances are that McTavish is involved. He’s currently pulling double duty as Father Kinley on Season 4 of “Lucifer” (which moved from Fox to Netflix) and on AMC’s fantasy Western “Preacher,” returning for its fourth and final season Aug. 4. McTavish is back as the Saint of Killers, a supernatural bounty hunter/cowboy summoned from hell to hunt the show’s titular preacher, Jesse Custer (Dominic Cooper).

McTavish teases a “shocking” end for the Saint of Killers that’s true to the comic book series on which “Preacher” is based.

“If anyone has read the comics it is … highly faithful [to them],” McTavish says. “I was very particular about that. As a fan of the comic, I felt it was extremely important that they translate it to the screen. Without giving it away, it is genuinely shocking.”

Saint of Killers aside, even though McTavish’s Dougal MacKenzie was only on “Outlander” for its first two seasons — Dougal was killed by his own nephew, Jamie Fraser (Sam Heughan) — McTavish says that’s the role for which he’s most often identified.

“It’s an extraordinary thing. ‘Outlander’ just has a long-term effect and it just keeps growing,” he says of the series, now in production on its fifth season. “So there’s just this mushrooming effect of that show. And also because unlike in ‘Preacher,’ I look [like the character]. There’s no makeup or wig. When people recognize me and tell me how it affects them, that really is the reason people go in for acting. Not necessarily for it to make you a well-known figure, but for the characters that you play to affect others.”

McTavish, who lives in New Zealand with his wife and daughters, says that appearing in so many genre shows was not an intentional career choice.

“I wish I could say it was planned, but it really wasn’t,” he says. “It’s all swords, sorcery [and] fighting enormous mythical creatures. It’s like I’m still 12 inside. There’s a huge part of me — and I think it’s true of almost anyone if they’re honest enough to admit it — that’s forever trapped in their childhood, in a good way.

“I think actors are given license to connect with that more readily than others.”
