Rachael Taylor and Amaury Nolasco have signed on to Transformers for DreamWorks and Paramount.

The film, directed by Michael Bay, is the live-action adaptation of the 1980s Hasbro toy line of giant robots that morph into cars, trucks, planes and ships. The trio join the already cast Shia LaBeouf, Megan Fox, Josh Duhamel, Jon Voight and Bernie Mac. The Hollywood Reporter says Taylor will play Maggie Marconi, a codebreaker at a think tank; Nolasco and Gibson are Army officers.
