Hey Sean, what's up with the towel?

Sean Edward Lewis is used to doing underground theater. With his ensemble Lilac Co. and St. John’s Theatre, he’s performed primarily in a church basement in Greenpoint.

Recent productions have brought the theater group above ground to Zebulon in Williamsburg and Storefront Space in Greenpoint. That’s where you can see them in their next production, a work in progress about cops and coping called “Cop Piece.”

The original serial drama follows a beat cop and a detective as they stake out a pizza joint in New York.

“It’s fun for the whole family — if you’re over 17,” said Lewis, who pulls an Orson Welles by writing, directing and starring in the production.

Of course, great theater is a mystery — one that was not exactly solved by the bizarre press photo that Lewis sent over: it showed him, wearing only a towel, by the side of a cheap motel pool. What’s up with that?

“I can’t talk about that,” said Lewis. You’ll just have to figure out that piece for yourself.

“Cop Piece” runs Fridays and Saturdays in April, as well as May 1, at 8:30 pm at Storefront Space (94 Norman Ave. at Manhattan Avenue, no phone). There is a $10 donation. For info, visit www.stjohnstheatre.org.
