When this special from the American Film Institute premiered, on TBS in June, I called it the most entertaining of all the AFI career salutes ever televised – and as a long-time, fervent, not-dead-yet movie fan, I’ve seen all 45 of them. What makes this one even more special of a special than the others? Watch and see. I tweeted then that TBS had to repeat it, it was so good. But I was wrong. TBS isn’t repeating it. Sister network TCM is, tonight – and if you missed it last month, don’t make the same mistake twice. Steve Martin and Martin Short set the stage with a classic musical comedy routine, and the guests gathered to honor, and talk about, Keaton include everyone from Al Pacino and Warren Beatty to Meryl Streep and Jane Fonda, with a surprise appearance by Woody Allen (pictured), who delivers a perfectly timed, affectionately playful one-man roast of Diane Keaton, who deserves all the accolades and attention. Two Keaton movies follow – one later in prime time, one much, much later tonight.
