A trio of play revivals is circling Broadway — none with officially confirmed dates, and each on the books with a differing degree of likelihood.Perhaps the most solid bet is a fall 2011 revival of “Death of a Salesman” toplined by Philip Seymour Hoffman and helmed by Mike Nichols. The director has openly talked about his plan to stage the show next fall, and Linda Emond (“Homebody/Kabul”) is said to be lined up to play Loman’s wife. Besides, word is the in-demand rights to the Arthur Miller classic are locked in. Legiters are quick to point out that Hoffman, at 43, makes for a notably young Willy Loman, the titular salesman in his final days. The previous thesp to headline the play on Broadway, Brian Dennehy, was 60 when he appeared in the 1999 revival. On the other hand, Lee J. Cobb, who originated the role in 1939, was 37. Nichols and Hoffman previously worked together in the 2001 Central Park staging of “The Seagull.” Also penciled in for 2011 is a revival of 1972 Jason Miller play “That Championship Season.” That one hasn’t been cast yet, but talks with potential actors are said to be further along on “Season” than they are on the other revival aiming for this spring, “Arcadia.” Gregory Mosher, who helmed last season’s revival of “A View From the Bridge,” starring Liev Schreiber and Scarlett Johansson, is onboard to direct. Producers are hoping to pull the production together sooner rather than later, with a casting notice citing January as the target start-date of rehearsals. According to one legiter involved in the brewing production, any speculation that Schreiber is attached to “Championship” is incorrect. Play chronicles a gathering to celebrate the 20-year anniversary of a high school basketball championship attended by four former members of the team and its coach, who is terminally ill. And then there’s “Arcadia,” which Billy Crudup has talked up in the press and which David Leveaux (“Cyrano de Bergerac”) has been tapped to direct. Tom Stoppard’s time-jumping 1993 play concerns contempo scholars studying the lives of the 19th-century figures who lived in a Derbyshire country house. With casting not far along, however, a spring berth is certainly possible, but it’s not a sure thing. Crudup appeared in the play’s 1995 Broadway bow. He’d return to the play in a different role, the academic first portrayed on the Rialto by Victor Garber.
