Ex-'Angel' Liu joins force at 'Southland'

Lucy Liu has joined TNT's "Southland," credited as a special guest star but with designs on her appearing regularly.

Liu will appear throughout the cop drama's fourth season, premiering in January, as a member of the Los Angeles Police Department. She recently completed filming "The Man with the Iron Fists," scheduled for release later this year.

"Southland" represents Liu's biggest TV series commitment since playing attorney Nola Lyons on ABC's "Dirty Sexy Money" in 2008-09.
