Time to saddle on up and head over to Casting Call Fields, to see which actors are getting rustled up for which Hollywood movies. Don't look away while the casting director brands their actors with the iron, unless you're a yellow-bellied coward.

Olivia Munn has officially joined Aaron Sorkin's HBO drama about what happens behind-the-scenes - whoa, there's a behind-the scenes? - at a cable news show. Currently the series is called "More As The Story Develops." When I wished I could "see more" of Olivia Munn, her suddenly getting a lot of acting work was not what I had in mind. Stupid monkey's paw. Meanwhile, Allison Pill (Milk) joins the cast as an associate producer in a shaky relationship with another staffer. The reason the relationship's shaky? He accidentally asked her to give him some "forehead." (Hollywood Reporter)

The old and buster Spider-Man, Topher Grace, is set to star in Gently Down The Stream along with Robert De Niro, Diane Keaton, Amanda Seyfried and Katherine Heigl. He'll play De Niro's son, who falls in love with his adopted brother's Latin sister. Eh, that kind of thing happens all the time, I'm sure. Justin Zackham is directing. (Deadline)

Rapper / actor / vitamin water aficionado 50 Cent will play blind DJ Shamus Cocobolo in Stephen SommersOdd Thomas. Yeah, that does sound odd. Based on the bestseller by Dean Koontz, the film's about a clairvoyant short order cook (Anton Yelchin) who follows around a suspicious man connected to an impending disaster. Odd Thomas also stars Addison Timlin, Willem Dafoe and Patton Oswalt. (Variety)
