'Boardwalk Empire,' 'Bored to Death' and more HBO fall premieres (including two on Mondays)

HBO will try to stake out a place for original programming on Monday nights in the fall with a pair of comedies.

The third season of "Bored to Death" and the new comedy "Enlightened" will form a one-hour block at 9 p.m. ET Mondays starting Oct. 10. HBO hasn't aired original series on any night other than Sunday in several years -- since the final season of "Six Feet Under" aired on Mondays in 2005, to be exact.

But HBO has five series on the air in the fall, and since it doesn't air shows before 9 p.m. ET in on Sundays, they won't all fit in primetime. HBO co-president Richard Plepler also notes that about half of the viewership, and sometimes more, for original series comes from repeat airings, DVRs, on-demand and HBO Go, so he's fairly confident an audience will find the Monday shows.

In addition to "Bored to Death" and "Enlightened," HBO will also roll out three other shows in the fall -- all on Sunday night. "Boardwalk Empire" will begin its second season at 9 p.m. ET Sept. 25, and two more comedies, "Hung" and "How to Make It in America," will air at 10 and 10:30 Sundays starting Oct. 2.

The new David Milch-Michael Mann drama "Luck," meanwhile, is slated to premiere in January 2012 in the spot formerly occupied by "Big Love."
