In her 70 year history, Wonder Woman has never made it to the big screen. Wonder Woman almost made it to television this fall, with legendary TV producer David E. Kelley behind it. A pilot was produced for NBC, but in the end, NBC decided not to go with it.
DC Comics recently redesigned Wonder Woman, giving her pants and a jacket to cover up her rather bare classic look. Once the show was dropped, the pants dropped too (no, not like that), with DC having no need of coordinating a look across media properties.
The pilot's leaked out online, so there are reviews available. The consensus seems to be that it was cheesy and not quite there, but that there are the sparks of something, particularly in the actress portraying Wonder Woman (also known for her work on "Friday Night Lights"), Adrianne Palicki. This generation apparently won't get the chance to watch a Wonder Woman TV show of their own.
