The cast of "Angel" will celebrate the show’s 20th anniversary with a panel at New York Comic-Con this fall -- minus Angel himself, David Boreanaz.

On Tuesday, NYCC announced that series stars Charisma Carpenter,James Marsters, J. August Richards,Alexis Denisof and Amy Acker have been confirmed for the convention, which runs October 3-6.

Noticeably absent from that list is Boreanaz, who first played the vampire with a soul on "Buffy the Vampire Slayer" and then on his own series, which ran from 1999-2004 on the WB.

In March on "The Talk," he said that being there for an anniversary celebration might be tough: "I don’t foresee any major things happening. I just think that getting everyone together would be great. I don’t know how that would happen because there’s so much going on and I’m shooting."

Since "Angel,"  Boreanaz starred on the Fox series "Bones" from 2005-2017. The third season of his CBS series "SEAL Team" returns October 2, which is likely why he can't make the Comic-Con event.

A "Buffy" reunion happened earlier this year, sans creator Joss Whedon and Buffy star Sarah Michelle Gellar
