Early life

Marc Guggenheim was born and raised on Long Island, New York. He attended the University at Albany, State University of New York. His brother is screenwriter Eric Guggenheim.

Career

Guggenheim worked in Boston, Massachusetts, as a lawyer and part-time writer for five years.

Television

After a romantic comedy script led to a few meetings with producers, he moved to California to pursue a career as a screenwriter. A script for The Practice was his first produced work. He eventually served as a producer for Law & Order, Jack and Bobby, CSI: Miami, and In Justice.

With Greg Berlanti, Guggenheim is the co-creator of the ABC show Eli Stone. He later became executive producer of ABC's No Ordinary Family. Guggenheim, together with Berlanti and Andrew Kreisberg, adapted the Green Arrow comics into the television series Arrow, where Guggenheim serves as co-showrunner.

Comic books

He served as an intern at Marvel for a time in 1990 for editor Terry Kavanagh, and was the colorist for an eight-page Iceman/Human Torch story while there. His writing experiences also include the comic books Aquaman for DC Comics, Wolverine and The Punisher for Marvel, and scripts for the Rare Game Perfect Dark Zero. He wrote Blade for 12 issues with artist Howard Chaykin.

In 2006, Guggenheim took over the writing of The Flash. Guggenheim's run concluded with the death of the fourth Flash, Bart Allen.

In 2007, Guggenheim became one of the rotating team of writers on The Amazing Spider-Man. His first story appeared in Amazing Spider-Man #549. He also launched a creator-owned comic, Resurrection, for Oni Press.

He wrote the comic book Young X-Men for Marvel which was launched in April 2008, and in 2008 was working on a comic with Hugh Jackman and Virgin Comics, Nowhere Man, and on Super Zombies for Dynamite Entertainment and Stephen King.

He wrote the script for the 2009 video game X-Men Origins: Wolverine, developed by Raven Software, a video game based on the film of the same name.

Guggenheim was intended to take over Action Comics after the War of the Supermen limited series, but was replaced by Paul Cornell. Guggenheim instead worked on Justice Society of America.
