Guggenheim has been with the Arrowverse since the very start, as an executive producer on “Arrow,” “The Flash,” “Supergirl,” “DC’s Legends of Tomorrow,” and “Batwoman.” He was also one of the minds behind “Crisis on Infinite Earths,” the 2019 CW crossover event that brought many of the shows together for a multi-episode exploration of the multiverse (it even included character cameos from the 1966 “Batman series, “Smallville,” “Doom Patrol,” and other DC projects. So given that history of pulling everything together for the small screen universe, Guggenheim hoped for at least a meeting once the DC reboot process began.

“Not a job, mind you. A meeting. A conversation. A small recognition of what I’d tried to contribute to the grand tapestry that is the DC Universe. I’d only spent nine years toiling in that vineyard, after all. (Not including many more years co-writing the ‘Green Lantern‘ movie, a ‘Green Lantern’ streaming series, and comic books like ‘The Flash,’ ‘Batman Confidential,’ ‘Adventures of Superman,’ and ‘Justice Society of America.’)”

In the post, he goes on to lament that although working for DC was “creatively fulfilling,” it also involved “a lot of adversity, challenges, and personal sacrifices — none of which seem to have accrued to any professional benefit.”

“Simply put, the Arrowverse hasn’t led to any other gigs, so it feels — at least on a career level — that I really wasted my time.”
