“It won’t be the war to end all wars, it will be the war to end everything,” said David Tennant who portrays a demon of the coming Armageddon in the first official trailer for Good Omens that was unveiled at New York Comic Con Saturday. “Welcome to the end times,” added Michael Sheen, who plays an angel.

With a Queen soundtrack, the first peek at the upcoming Amazon series based on the 1990 end-of-the-world novel written by Neil Gaiman and Terry Pratchet was played at the end of a panel led by Sheen and Tennant in the theater at Madison Square Garden.

“It is like a dream come true for me,” Sheen told the audience of being in the Gaiman series. “I just have to put up with these terrible actors.”

“I did this for money, Amazon paid me so much money I said sure,” responded Jon Hamm, who plays the angel Gabriel.  After adding a few jokes, Hamm admitted that he’s a long time fan of Good Omens and Gaiman’s work.

“My favorite part of Good Omens was the paycheck,” Hamm later said.

Gaiman himself also tried to fend off a question about how the former Mad Man actor would be taking on the role of Batman. Tennant yelled out “how great would a Jon Hamm Batman be?” as the crowd roared.

The Whoopi Goldberg hosted panel, with co-star Miranda Richardson on stage as well, also saw Good Omens revealing a New York Comic Con exclusive poster and showing clips from the second episode of the six-parter.

Co-produced with the BBC, the six-episode Good Omens limited series is scheduled to debut in early 2019. Gaiman is also an active executive producer on American Gods, now in it’s second season.
