PASADENA, Calif. — Filling the oxfords of one of Britain's most famous gumshoes could make most actors quake with fear. But not Shaun Evans. When Evans was first approached about playing the cultured and cantankerous Inspector Morse as a young man, he had his doubts.

After all, John Thaw had portrayed the crossword puzzling Morse for 33 episodes over a span of 13 years. And it seemed the TV persona, which aired here on PBS, died with him when Thaw passed away in 2002.

Evans told his agent he'd like to read the books first and asked him to find out how many other actors were on the list to play young Endeavour Morse. (Yes, that was his first name, Endeavour.)

Evans was a voracious reader as a kid, a passion that helped earn him a scholarship to a vaunted high school in his hometown of Liverpool.

A day or two passed, and his agent phoned again. "'There is no list,' he told Evans, who was in Los Angeles. 'They're being very specific about just you playing the part.' So Evans read all of Colin Dexter's "Morse" novels.

"When I read the books, I thought, 'Here you've got a character who has reached his midlife. He's never married, seems quite unhappy in the choices that he's made in his life and in his general interactions with people. And so for me, I thought, "That's interesting. I wonder how we can get him at the beginning of that.'

"So by the time I did get back I had ideas about how I felt it would work out," he says.

Evans made it clear that he wasn't interested in doing an impression of Thaw. "I'm not your man for that. And I wish you the best with it," he told them. "I think they were kind of delighted by the fact that I'd taken the bull by the horns and read the books and had some ideas about it."

Those ideas will be evident on KUED-Ch. 7 Sunday at 8 p.m. when Evans dons the mantle of the 1960s Morse in "Endeavour" premiering on "Masterpiece Mystery!"

Evans, whose family hails from Northern Ireland, admits he's sometimes frightened to take on a new role. "You have a little bit of fear, but I think that's what's exciting," he says, shifting in the overstuffed leather chair.

"The idea of, 'Can I do this?' But it's a personal thing; it's not for anybody else. It's like you wonder if you can actually do this. You often have it, but it's a fleeting thing because the reality is you're trying to brainwash yourself so much with the script that you have in front of you and all of the different components of it. And (you want to) make sure your subconscious is working properly. You only have really one moment of like, 'Oh well, no.' I also think that that moment is very important because it's good. I'm challenging myself. This is good."

He's been challenging himself ever since he trekked to London at 18 to study acting at the Guildhall School of Music and Drama. "It forced me to grow up, and it also gives you an opportunity to see there is another world outside of the one that you've been brought up in," he says.

Evans' dad is a taxi driver, his mom a health care worker in a hospital. He has a brother 11 months his senior, whom he describes as slightly "wilder" than he was when they were kids. Evans, 32, says he was 26 when his heart was broken by a failed romance. But he isn't soured on the idea.

"I love the whole thing. In hindsight I love the heartbreak. But at the time, 'Ohhhh, this is awful.' 'Let's do it again.' 'Who's next?'" he laughs.

His grandfather's death last year added to his heartbreak, but bolstered him as well. "Part of being alive is dying as well," he says.

"But I remember thinking very specifically to make the most of things. To make the most of time with people we love. If you love people, tell them you love them. Don't be losing sleep over tiny things. Life is complicated enough."

So far things have been relatively calm for him. He says he's enjoyed a "good, anonymous" life. But asked if he's prepared for fame, he says, "I don't even think about it. I was surprised about the amount of interest in 'Endeavour' before we began to shoot. We did a photo shoot and the day after the photo shoot ... it was in the papers and on Sky News and I remember thinking, 'Wow.'

"I just turned my phone off and thought, 'Well, it'll pass.' I had more pressing things. I wanted to do a great job with the opportunity that I'd been given. And if you put too much pressure on the idea of people watching you, it stops you being able to watch people."

Sixteen new designers will be sewing darts and cutting fabric when "Project Runway" returns to Lifetime on July 19. Michael Kors, Heidi Klum and the annoying Nina Garcia will be back on their high horses as the designers pin and pink and drape their way to fashion fame on the popular reality show. This year, 10 of the new contestants live in New York, four reside in California with one from Kentucky and one from Minnesota. The oldest is 58, the youngest 22, and they hail from faraway places like the Ukraine, Guyana and Brazil.

Mentor Tim Gunn will be on hand to encourage the wannabes. When the show began, he says, it was anybody's guess how it would fare.

"Their ratings were so bad we didn't even know if it would run the full season," he says. "I never dreamed I'd be on camera. My initial role with 'Project Runway' was as a consultant. My role on the show didn't even exist. And it wasn't until the last second that they said, 'We'd better do something.' No one ever said this to me, but I speculated that the producers were worried that the designers would go into the work room and not speak. So by sending me in they were assured of some dialogue."
