'Doctor Who' is the best present

My favorite thing about Christmas is hands down new "Doctor Who" specials every year. This year marks Matt Smith's second outing and promises to be even more fun than last year's "A Christmas Carol."

These videos from BBC America offer a look at what Whovians can expect from "Doctor Who: The Doctor, The Widow and The Wardrobe" which premieres on BBC America Christmas Day at 9 p.m.

Check out the alien tree which looks like the creepiest thing since "Blink" where we met the Weeping Angels.

Up close at 'The Nerdist' taping

Tim and I were among the lucky few who got into the taping of "The Nerdist" end of the year special.

In addition to the always fun Chris Hardwick, Jonah Ray and Matt Mira, the guest list also included Wil Wheaton and Nathan Fillion.

As you would expect from a lineup that good, we had a spectacular time. It's always great to see actors like Wheaton and Fillion truly embrace and honor their nerd roots.

The crowd stayed amazingly enthusiastic throughout the taping and got particularly excited when the surprise special guest showed up.

While not giving away too many spoilers we can tell you there was some hilarious talk of how transporters work, the sentencing requirements for Arkham City and how Wil Wheaton invented non-linear editing.

"The Nerdist" end of the year special premieres Dec. 24 at 9 p.m. on BBC America following the "Doctor Who" Christmas special.
