TV Casting Roundup: "Heroes," "Bionic," "Big Shots"

• Really, guys, how many "Heroes" are there going to be? Today brings news that Jessica Collins, formerly of "The Nine," has joined the cast in a recurring role. She'll play Sophie, a "mysterious woman with powers" — who isn't, these days? — who works at the organization that's tracking the heroes. She'll join fellow "The Nine" alum Dana Davis on the show.
• Paul Blackthorne, most recently of Sci Fi's "Dresden Files," will appear this fall on ABC's guy-fest "Big Shots." His character will be the fifth CEO, a successful tycoon whom the other four CEOs — played by Michael Vartan, Christopher Titus, Dylan McDermott and Joshua Malina — envy.
• Linda Park, most recently of "Raines," will be a regular on "Women's Murder Club," playing a deputy district attorney.
• Bruce McGill, who's had supporting parts in pretty much everything, now has a recurring role on "Bionic Woman" as a powerful operative within the bionics program.
