The announcement comes on the day of Williams' appearance on "The Late Show with David Letterman" (May 13) and on the eve of the world premiere of Twentieth Century Fox Films' "Night at the Museum: Battle of the Smithsonian," in which Williams reprises his role as Teddy Roosevelt.
In a statement on his website Williams said, "This little break has given me more energy than ever. Plus it's wonderful to have a cow valve... If you don't mind the grazing, it's quite invigorating."
The tour, according to Williams' site, will resume Sept. 30 in Bloomington, IN, at the I.U. Auditorium.
New Broadway dates have yet to be announced.
Weapons of Self-Destruction, according to press notes, "highlights Williams' trademark free associations and riffs on social and political absurdities." For tour information visit www.robinwilliams.com.
Weapons was to have arrived on Broadway at the Neil Simon Theatre April 23, presented on Broadway by James L. Nederlander and Ron Delsener. The Broadway engagement was canceled due to Williams' heart surgery.
The actor-writer-comedian, who became known during his work in "Mork & Mindy" — a spinoff created from a guest spot on "Happy Days" — is widely hailed for his madcap improvisational humor in movies such as "Good Morning, Vietnam," "Aladdin," "The Birdcage," "Mrs. Doubtfire" and "Death to Smoochy," among others. Williams has often taken on dramatic roles as well in such films as "The Fisher King," "Awakenings," "Insomnia" and his Academy Award-winning turn in "Good Will Hunting." On stage the actor may be remembered for his performance as Estragon opposite Steve Martin's Vladimir in the Mike Nichols-directed production of Samuel Beckett's Waiting for Godot.
Williams was seen on Broadway in Robin Williams: Live on Broadway (July 11-14, 2002) and V.I.P. Night on Broadway (April 22, 1979).
