THE AFI’S LIFETIME ACHIEVEMENT tribute to Robert De Niro, June 12 at the Kodak, will have a June 23 USA airdate.

And in between (so far) are Leonardo DiCaprio, Harvey Keitel, Chazz Palminteri, Ben Stiller, Don Rickles, Joe Pesci, Juliette Lewis and Edward Norton. Bob Gazzale will exec produce and Louis J. Horvitz directs. Meanwhile the AFI’s Silver Theater and Cultural Center in Silver Spring, Md., which was christened by Clint Eastwood April 4, with one of his favorite pics, William Wellman’s “The Ox-Bow Incident,” has to date attracted 2,500 AFI Silver Charter Members for the state-of-the-art complex … Robin Williams intro’d (he did a half-hour!) the authors-on-music group, the Remainders, at SanFran’s Fillmore, which raised $100,000. And the group, with Steve Martin on banjo and hosting, raised another charity-bound $65,000 at the . Times Festival of Books, Saturday with the dough going to America Scores, an after-school creative writing/soccer program. The Remainders authors take a week off writing for their own version of a Rock ‘n’ Roll Fantasy Camp … The “Temple of the Air,” was launched Thursday at the BevHills’ Four Seasons Hotel with an SRO dinner screening of its first program created by the Temple Shalom for the Arts’ Rabbi David Baron. The DVD (or tape) will be available to the homebound, the nation’s Jewish Homes for the Aging as well as to the public and will be also screened on Hallmark Oct. 5, Yom Kippur Eve. The initial program was funded by Allen and Anita Kohl and the Bob and Bobbie Stern families. Among those seen on the TV program are: Jason Alexander, Mary Hart, Leonard Maltin, the late Nell Carter and Monty Hall (who also ’d the launch party), Theo Bikel (who also sang and accompanied himself on guitar and dueted with Cantor Ilysia Pierce) and comedian Steve Landesberg of “Barney Miller.” The “Temple of the Air” follows with programs on Chanukah and Passover for those who are homebound — or not, as well. The aim is to distribute more than 1,000 tapes (or DVDs ) to the Homes for the Aging nationally.
