Los Angeles ? It’s a dramatic shift, when funny men turn serious. Even Eddie Murphy, the latest of Hollywood’s top comic performers to try, has had some laughs about his own transformation, which could bring him an Academy Award.

At the Screen Actors Guild awards, where he won yet another supporting-actor prize for “Dreamgirls” amid the buildup to Oscar night, Murphy copped a British accent as he soberly remarked how honored he was to be recognized by his peers.

Murphy could not keep the wiseguy with the broad grin in check for more than a few seconds, though.

“No, I’m sorry,” Murphy said after a moment, cracking up with laughter. “It’s just when the British people come and get the awards, it’s so smooth with their stuff. And I feel goofy up here, ’cause I don’t be winning stuff.”

And most comic actors don’t be winning stuff like an Oscar when they turn in a worthy serious performance. Some, like Will Smith, Dan Aykroyd and Bill Murray, at least can get nominated. Others, such as Steve Martin, Jim Carrey or Adam Sandler, never get that far.

Yet Murphy looks as though he will follow “Dreamgirls” co-star Jamie Foxx, the best-actor recipient two years ago, as an actor who started in comedy and made good with a dramatic role.

Murphy also won the Golden Globe and Critics’ Choice awards as supporting actor for “Dreamgirls,” a role that let him cut loose with a twist on his blistering James Brown impersonation from his stand-up and “Saturday Night Live” days.

As 1960s and ’70s soul singer James “Thunder” Early, Murphy also displays a dark side, portraying with tragic restraint a doomed man whose desires to venture beyond his showy pop persona are thwarted.

It’s not as though Murphy was revealing some inner pain he’s been carrying since he shot to celebrity at age 19 on “Saturday Night Live” and became one of the most resilient movie stars of modern times.

“I can’t relate to the tragic side of Jimmy Early. I have the closest you can get to having a charmed existence in this town,” Murphy, 45, told Associated Press Television News. (Murphy will do some TV interviews but generally declines print interviews, including a request for this story.)

Unlike comedic roles that might benefit from his improvisational wit, “Dreamgirls” had Murphy sticking largely to the script.

Eddie Murphy could win his first Academy Award for his work in Dreamgirls. The dramatic role is a change of pace for the longtime comedian.

“I was in completely uncharted waters doing a movie like this, so I wasn’t as quick to improvise, because they are not going for the joke,” Murphy told APTN. “My character has some moments when he is funny, but he is really this tragic figure, how he winds up. He is kind of cool and charismatic in the beginning, but he wasn’t really supposed to be that funny, so I wasn’t doing a lot of improvising.”

Turmoil in Murphy’s private life clearly helped him capture Early’s anguish, “Dreamgirls” director Bill Condon said. During filming, Murphy was enduring the breakup of his 12-year marriage.

“No question, he was being wiped out emotionally,” Condon said. “He would talk about the fact he was glad to have to channel some of this into the part and how he almost wished he was doing a completely serious, full-on drama, because he could take all that pain and kind of channel it there.”

After establishing himself as one of the biggest box-office draws of the 1980s and early 1990s with “48 Hrs.,” “Trading Places,” “Coming to America” and the first two “Beverly Hills Cops” flicks, Murphy has seesawed through hits and flops for more than a decade.

In the mid-1990s, Murphy pulled himself out of the box-office doldrums with “The Nutty Professor,” followed by a sequel, “Nutty Professor II: The Klumps,” in which he went the Peter Sellers route by playing multiple roles, a feat he pulled off in such films as “Coming to America.”

The depth Murphy displays in “Dreamgirls” should come as no surprise considering the versatility he has shown in comedy, colleagues say.

“He already should have gotten every award there is for just ‘The Klumps,”‘ said Foxx, an Oscar winner for “Ray” who counts Murphy among his major influences. “Unfortunately, comedy’s not always looked upon as Oscar-worthy.

“But when you look at what he did in ‘Coming to America,’ you look at what he did in ‘Nutty Professor.’ The guy plays all these characters, and you actually believe these characters exist. And it’s just this one dude.”
