Two new mini-sites dedicated to Fantastic Four are now live at Marvel’s official page — one for the upcoming Fantastic Four: Rise of the Silver Surfer theatrical feature, another for the Fantastic Four: World’s Greatest Heroes – Back in Action animated series.

Both sites contain a trailer, downloadable wallpaper, cast details, background story information, tidbits, and a countdown clock to their respective debut dates.

The site dedicated to the FF animated series, which originally ran last year on the Cartoon Network, also has synopses for seven episodes.

Fantastic Four: Rise of the Silver Surfer sees the return of Ioan Gruffudd, Jessica Alba, Chris Evans, and Michael Chiklis as the superhero group, and Julian McMahon as their nemesis Dr. Doom. In this sequel to 2005’s Fantastic Four, which hits theaters on June 15, 2007, the Fantastic Four faces for the first time the Silver Surfer, who threatens the safety of the entire planet.

The FF animated series World’s Greatest Heroes returns to the Cartoon Network on June 16, 2007. The first four episodes are out now in the Vol. 1 DVD.
