Superman has found his Lois Lane and his Lex Luthor.

Kate Bosworth is in negotiations to play the Man of Steel's plucky fellow reporter, and Kevin Spacey is set to play the superhero's nemesis in Bryan Singer's Superman movie for Warner Bros. Pictures.

The comic book movie would reunite the two actors, who currently appear in Spacey's "Beyond the Sea" as Sandra Dee and Bobby Darin.

The casting of Bosworth was a long process that ultimately rested on a chemistry test between the actress and Brandon Routh, who is playing Superman, sources said. Bosworth reportedly beat out the likes of Claire Danes, Linda Cardellini and Michelle Monaghan.

Sources said Singer wanted Spacey early on but that the Oscar-winning actor's commitment to London's Old Vic Theatre, where he is artistic director, caused scheduling snafus on the road to making a deal. Spacey, who is in rehearsals for "National Anthems" at the Old Vic, will do a limited run of "The Philadelphia Story" at the theater before moving to the Superman movie, which has a March start date.

Polly Cohen is overseeing for the studio.

Bosworth will next be seen in Fox Searchlight's "Bee Season" and is repped by UTA, One Management and Offer Webber Dern.

Spacey, who next appears in Millennium Film's "Edison," is repped by WMA, manager Joanne Horowitz and attorney Stone Meyer Genow.
