Channel Surfing: Zach Gilford Goes Off the Map, Entourage to End Next Year, Fringe's Sebastian Roche to Supernatural, and More

Welcome to your Monday morning television briefing.

Former Friday Night Lights star Zach Gilford has joined the cast of ABC's midseason medical drama Off the Map, from executive producers Shonda Rhimes and Jenna Bans. TVGuide.com's Natalie Abrams reports that Gilford will play Tommy, a physician who travels to a remote medical clinic in South America along with fellow doctors Lily (Caroline Dhavernas) and Mina (Mamie Gummer). (The series' other stars include Martin Henderson, Jason George, and Valerie Cruz.) Gilford's casting comes on the heels of the hiring of Rachelle Lefevre as a regular and the departure of Enrique Murciano, though ABC was quick to point out that Gilford won't be playing the same role that Murciano did, a spoiled and uptight plastic surgeon.

Not a moment too soon: HBO's long-running comedy Entourage will end next year, according to HBO Co-President Richard Plepler, speaking at Saturday's Television Critics Association Summer Press Tour session for the pay cabler. "The plan right now is to finish up this season and we're not clear exactly how many [episodes], we'll do a shorter order next season to finish up," said Plepler on Saturday. "We had talked about six [episodes]... [Creator Doug Ellin] wants to write [an Entourage] film but he also wants to do it so the storytelling makes sense... But Entourage next summer will definitely be the final season." To parse the meaning of Plepler's words: Entourage has got one more brief season left it in--likely six episodes or so--before it ends and there could be a movie but it's not certain yet.

Fancast's Matt Mitovich is reporting that Sebastian Roche (who recurred this season on FOX's Fringe as Thomas Jerome Newton) has ben cast on the CW's Supernatural, which returns this fall for its sixth season. Roche will play Balthazar, an angelic friend of Misha Collin's Castiel, in the season premiere ("The Third Man"). “Remember when Cass was dragged back to Heaven as a prisoner? Balthazar was actually the only friend who stood up for him,” executive producer Sera Gamble told Mitovich. “During the Apocalypse, Balthazar went AWOL, and Cass thought he was dead. Turns out… not so much.” Meanwhile, Roche will also be back on Fringe this fall as Newton hasn't quite finished with the Fringe team. (Fancast)

Keck also reports that Armand Assante will reprise his role as Goya in the fourth episode of the season when the gang visits him on the island that he inhabits. (TV Guide Magazine)
