The distinguished Shakespearean actor, in Chicago for the Official Star Trek Convention, found time to sit in with the all-male group that vamps an entire play, Bard-style, based on an audience suggestion.
On this night, the title was "The Taming of Winnie-the-Pooh," and the British actor -- no doubt familiar with the tales set in England's Hundred Acre Wood -- fell into the role of Christopher Robin. "He was amazing," said iO owner Charna Halpern. "He didn't miss a beat."
By show's end Stewart had slain the evil King Pooh, won the heart of a maiden (played by company regular Blaine Swen) and inhabited four other characters.
It wasn't his first time riffing Elizabethan dialogue with the group. As co-host of "The Second City Guide to the Opera" at the Civic Opera House in January, Stewart joined Improvised Shakespeare for a brief set, and a week later he was part of the actors' road gig in New York.
