We’ve got a couple of casting stories to share with you this afternoon. First up, Sienna Miller and Brendan Fraser are the latest additions to A Case of You. Justin Long co-wrote, will produce and star in the indie set in the world of online dating. Long plays “a young writer who tries to impress a girl he meets online with an embellished profile, but finds himself in a real mess when she falls for him and he has to keep up the act.” Variety's report doesn't specify what roles Miller and Fraser will fill, but they join an impressive cast that includes Peter Dinklage, Evan Rachel Wood, Busy Phillips, and Keir O’Connell. Production is currently underway in new York with director Kat Coiro.

Hit the jump for casting news concerning the next entry in the Percy Jackson series.

Additionally, Variety reports that Big Love star Douglas Smith is in talks to join the next Percy Jackson film. Logan Lerman and Alexandra Daddario return for Percy Jackson & the Olympians: The Sea of Monsters, which finds Percy (son of Poseidon) and his demigod friends heading to the Island of the Cyclopes (which, in our case, is the Bermuda Triangle – neato!) in order to retrieve a Golden Fleece. Chris Columbus, who directed the first film, is stepping back into a purely producer role on the sequel. Thor Freudenthal (The Diary of a Wimpy Kid) will take the helm, with a release date set for March 26th, 2013. Read a synopsis of the novel below:

After a summer spent trying to prevent a catastrophic war among the Greek gods, Percy Jackson finds his seventh-grade school year unnervingly quiet. His biggest problem is dealing with his new friend, Tyson—a six-foot-three, mentally challenged homeless kid who follows Percy everywhere, making it hard for Percy to have any “normal” friends.

But things don’t stay quiet for long. Percy soon discovers there is trouble at Camp Half-Blood: the magical borders which protect Half-Blood Hill have been poisoned by a mysterious enemy, and the only safe haven for demigods is on the verge of being overrun by mythological monsters. To save the camp, Percy needs the help of his best friend, Grover, who has been taken prisoner by the Cyclops Polyphemus on an island somewhere in the Sea of Monsters, the dangerous waters Greek heroes have sailed for millennia—only today, the Sea of Monsters goes by a new name…the Bermuda Triangle.

Now Percy and his friends—Grover, Annabeth, and Tyson—must retrieve the Golden Fleece from the Island of the Cyclopes by the end of the summer or Camp Half-Blood will be destroyed. But first, Percy will learn a stunning new secret about his family—one that makes him question whether being claimed as Poseidon’s son is an honor or simply a cruel joke. [Amazon]
