New York is a tough town. The competition there is cutthroat, whether you're looking for a job, a parking space or even a seat at a good restaurant. One would think that with hundreds of bars, restaurants and clubs in the city to choose from, businesses would be competing for customers. But most of the time, it's the other way around. People have to prove themselves worthy of the particular club or restaurant they want to get into. Oh, and in New York, the customer is always right, especially if they happen to be Naomi Campbell.

This kind of competition is the force behind the Arizona Theatre Company's current production, "Fully Committed." Bob Sorenson stars in this one-man play as Sam, a struggling actor who works as a reservation booker at a very exclusive restaurant. Reservations must be made at least three months in advance, but that doesn't stop VIPs and people who think they're VIPs from whining, begging or buying their way to a table.

Sorenson, who also appeared in the Arizona Theatre Company's production of "Ghosts," plays dozens of characters during the play. His voice seamlessly morphs into the high-pitched whine of a Manhattan matron, the faux British accent of a cat-stroking socialite and the "fugeduboudit-eh?" speech of New York Mafioso. Sorenson shifts into each of these characters while keeping up Sam's end of the conversation, without ever missing a beat. He also manages to keep his voice distinct, so the audience has no trouble guessing who Sam is talking to, who he's got on hold and who just hung up on him.

It's worth seeing "Fully Committed" just to watch Sorenson juggle all these characters. The play's mix of high-brow and low-brow humor kept the audiences smiling and laughing for the entire show. While it was easy to recognize why many of the conversations between Sorenson and the callers were funny, it's not so easy to imagine this play appealing to those under the age of 25. But then again, this may be the only time one finds something even remotely close to toilet humor at the ATC.

The Arizona Theatre Company has $10 tickets for anyone under the age of 25, so for about the price of a movie, one can experience live theater. Seeing Sorenson pull off his acting acrobatics live makes acting on film seem downright easy in comparison. This is the last weekend to see the play in Tucson. Call 622-2823 for ticket information.
