In a showdown worthy of a company crossover, the Dark Knight Detective and ol' Shellhead will face off against each other in seven categories, including "Best Actor" (Christian Bale vs. Robert Downey Jr.), "Best Actress" (Maggie Gyllenhaal vs. Gwyneth Paltrow), "Best Supporting Actor" (Heath Ledger vs. Jeff Bridges), "Best Director" (Nolan vs. Favreau), "Best Writing," "Best Music" and "Best Special Effects."

Adding to the strong comic book showing at this year's awards are nods for "Hellboy II: The Golden Army" (up for two awards, including "Best Horror Film") and "Wanted" (nominated for "Best Fantasy Film").

The 35th Annual Saturn Awards -- which will be announced on June 25, 2009 -- recognizes the best contributions to genre film, television and home entertainment.
