No matter what happens at next Sunday’s Tony Awards, you can bet that Kevin McCollum and Jeffrey Seller will be back at work on Monday morning. They are among the busiest and most successful theatrical producers, with a knack for finding musicals that resonate with contemporary audiences.

The two produced “Rent,” which will close in September after 12 years on Broadway; “Avenue Q,” which is still running after more than 2,000 performances; and, most recently, the ebullient hip-hop musical “In the Heights,” which is up for 13 awards on Sunday, including Best Musical and Best Performance by a Leading Actor in a Musical, for its creator and star, Lin-Manuel Miranda. (The third major producer of “In the Heights,” both off-Broadway and on Broadway, is Jill Furman.)

Messrs. McCollum and Seller are now at work on their next two productions: “[title of show],” a musical about the making of a musical, which opens on Broadway next month, and an Arthur Laurents-directed revival of “West Side Story,” which will open in Washington in December and on Broadway in February 2009. The revival will be faithful to Leonard Bernstein’s music and Jerome Robbins’s choreography, but Mr. Laurents will be updating his script by giving the Sharks some dialogue in Spanish. Recent audition notices in Back Stage noted that actresses auditioning for the role of Maria should be bilingual.

In an interview, Mr. McCollum attributed the success of “In the Heights,” which follows a weekend in the life of a community in Washington Heights, to its being a quintessentially American story. While many people have compared it to “West Side Story,” Mr. McCollum sees it as closer in spirit to “Fiddler on the Roof,” with its focus on the complex process of assimilation.

“It’s about realizing that we’re all connected,” he said. “All of us came from somewhere, and we are all looking for our home.”

Mr. McCollum likes to mention that he himself grew up in Hawaii, where he attended elementary school with Senator Obama. And “In the Heights,” with its optimism and youthfulness, certainly shares something of the spirit of the Obama campaign.

“We’re an amalgam of cultures, and that’s what the musical celebrates,” Mr. McCollum said.

“West Side Story,” with its story taken from “Romeo and Juliet,” could hardly be called optimistic, but it does probe issues of community and identity. A Broadway revival has been discussed for years, but issues of scheduling and creative control have scuttled earlier efforts.

“You have two estates [those of Bernstein and Robbins] and two living people [Stephen Sondheim, who wrote the lyrics, and Mr. Laurents], all of whom are very strong creative personalities — even the dead ones — and they all have to agree,” Robbins’s biographer, Amanda Vaill, said of why earlier attempts to revive the show had failed.

Mr. McCollum said that adding Spanish dialogue not only will make the production more contemporary, but will emphasize the conflict and misunderstanding between the Sharks and the Jets.

“When someone is next to you not speaking the same language, you’re immediately shut out,” he said. “It relates to a sense of belonging, of someone making me feel like I don’t belong in my own neighborhood.”

And this isn’t all that Mr. McCollum and Mr. Seller have on their plates. Mr. McCollum declined to comment to The New York Sun on whether he and his fellow producers are negotiating film rights to “In the Heights,” but, with its young cast and urban setting, the show would seem a natural for film. If it picks up several of the big awards on Sunday, you can expect to hear more very soon.
