Aaaand then he somehow got to do something entirely of his own creation... this little show called ''Series/BabylonFive''. You may have heard of it.

Afterward, he attempted to continue spreading the joy with high-concept shows like ''Series/{{Crusade}}'' and ''Series/{{Jeremiah}}'' - but the networks had by then decided that he was an enemy, and have since taken ''[[ToThePain special]]'' care to [[ScrewedByTheNetwork screw with him]].

He then started writing for comic books, and has had somewhat more success, most notably ''ComicBook/BulletPoints'', [[ComicBook/JMSSpiderMan his run on]] ''ComicBook/SpiderMan'' (which included the famous 9/11 issue and ''ComicBook/OneMoreDay''), ''ComicBook/MidnightNation'', ''ComicBook/RisingStars'', ''ComicBook/SilverSurfer: Requiem'', ''SupremePower'', as well as a return to ''Series/TheTwilightZone'' for Dynamite Comics. More recently, he wrote the screenplay for the Creator/ClintEastwood-directed, Creator/AngelinaJolie-starring ''Film/{{Changeling}}'', and his current projects include writing a script for a Literature/{{Lensman}} movie, the remake of ''Film/ForbiddenPlanet'', and at least one pass at a ''Film/WorldWarZ'' treatment. He handled a revival of one of Marvel's primary series, ''ComicBook/TheMightyThor'', as a lead-in to the next CrisisCrossover. He even got to write for the ''Film/{{Thor}}'' movie, even managing a cameo (he's the first guy to find Mjolnir and try to lift it). Truly an AscendedFanboy. He also wrote ''Film/UnderworldAwakening'', the fourth installment of that series. (He also wrote an episode of the ''Series/LogansRun'' TV series, but let's not talk about that.)

His first name is Joseph and friends call him Joe, but he has stated that "Joe Straczynski" is a name that would "frighten cats." Professionally, he goes by J. Michael so as to allow people to work up to the "Straczynski." First word: one letter, easy; second word: Michael, two syllables but familiar enough; then...the leap. Fans generally know and refer to him just by his initials, which is how he signs his emails and Usenet posts.

He spent some time in a cult while in college, and was once mugged and left near death. Both experiences heavily inform his stories.

He is currently writing the ''ComicBook/SupermanEarthOne'' graphic novels for DC Comics, as well as a number of creator-owned comics under the "Joe's Comics" banner for Image Comics. He previously had a short run in the ''Franchise/{{Superman}}'' comic book as writer of the story arc ''ComicBook/SupermanGrounded''. However, he stopped working on the book in order to write the ''Superman: Earth One'' books. Since then, Chris Roberson completed the arc. He co-created and co-wrote Creator/{{Netflix}}'s upcoming ''Series/{{Sense8}}'' with [[Film/TheMatrix the Wachowskis]].

Shares a birthday with Creator/DavidHasselhoff and Creator/PhyllisDiller.
