Austin Nichols has inked a talent holding deal with HBO. Under the pact, Nichols will be cast in a drama or comedy series project for the premium cable channel. The deal is somewhat unusual for HBO, which rarely signs actors to holding deals. Nichols recently appeared on HBO's drama "Deadwood" and the Walt Disney Pictures feature "Glory Road." His other credits include the features "Wimbledon" and "The Day After Tomorrow" and a multiple-episode arc on HBO's drama series "Six Feet Under." Nichols is repped by UTA and Joan Green Management.
