TV WORTH BUYING: Ricky Gervais' 'Extras' at deep discount

Another sterling DVD deal from Amazon for Wednesday only -- Ricky Gervais' entire Extras series for $15!

That's both six-episode seasons and the feature-length conclusion of the original The Office creator-star's achingly funny portrait of a two-bit movie extra who suddenly becomes a sitcom star/hack. Has he really realized his dreams?

This HBO effort is just as sharp and poignant as Gervais' BBC The Office was. And that's more than worth a look, too. (Even if it's not as great a sale.)
