'Southland' Actor Shawn Hatosy Joins 'Dexter'

Shawn Hatosy is heading back to 'Southland,' but not before joining the cast of 'Dexter' for a multi-episode arc.

According to the Ausiello Files, Hatosy may portray a no-nonsense FBI agent, based on a recent casting call. A rep for Showtime declined to give the full details.

In the meantime, 'Southland' fans shouldn't worry too much: According to the report, Hatosy will return to the TNT series -- which was recently picked up for a 10-episode third season -- right after filming on 'Dexter' concludes.

Hatosy isn't the only new face set to appear on 'Dexter''s upcoming fifth season. 'Save the Last Dance' actress Julia Stiles is also joining the cast, playing a mysterious young woman who forms a relationship with the titular character, played by Michael C. Hall.

As previously reported, the new season will also see the return of Julie Benz. Her character, Rita, was killed in the season 4 finale. Benz is reportedly scheduled to appear in the season premiere.

The fifth season of 'Dexter' is set to premiere in September.
