You don't have to watch "Doctor, Doctor" for long before you discover that something strange is going on.

Oh, the show has a script. But star Matt Frewer has a tendency to deviate from the written word."Every time we shoot, we do each scene . . . probably three times. And thanks to (Frewer), not one of them is ever the same," said executive producer Norman Steinberg.

Frewer stars as Dr. Mike Stratford, an off-the-wall general practitioner in network television's most off-the-wall show.

"The deal that we made was that I would let him go as long as he allowed me to tell him when I thought it didn't work, or when he strayed off the story line," Steinberg said.

As Stratford's personality was originally written, "It was probably more an eccentricity . . . than out-and-out craziness," Frewer said.

All of this craziness is hardly what is expected of a trained Shakespearean actor. Although Frewer is perhaps best know for portraying Max Headroom, he spent 10 years in London stage productions like "Much Ado About Nothing" and "Romeo and Juliet."

"When I was over in England, I was a classically trained actor, dear boy, which explains my slouch and my slur," Frewer said. "I was doing an awful lot of stuff over there and I think it started largely as a reaction to being straitjacketed in the kind of iambic pentameter thing. Thee and thou, you know how it is."

"And I did all that stuff and then felt somewhat hamstrung by the sort of stuff I was doing - that you couldn't let rip with . . . those rhyming couplets."

He said he also feels that British humor rubbed off on him during his time in England.

"Well, I like the Monty Python stuff. I mean, that was probably some kind of an influence. But not consciously," he said.

And his sense of humor comes naturally.

"Actually, I think my dad's pretty funny. He's got a very good sense of humor, very sort of off-center and strange. He keeps pressing me to be on the show and he's got a stage name worked out - Bolt Upright," Frewer said.
