1.  He started out as a short-term companion of Doctor Who on the series of that name in 2005.  (The new Doctor Who series returns to the US September 1.  Nothing to do with Captain Jack, but it had to be said.)  Oh, and his last name is apparently taken from Agatha Harkness, a Marvel Comics character.

2.  He’s originally from the 51st century, although we tend to see those of his adventures which took place in the 21st century (although not exclusively those).

3.  He can’t die. Oh, he can be killed, but he comes back to life almost immediately.  That sounds cool, but it very definitely has its drawbacks.

4.  What kind of drawbacks?  Well, at one point he is buried alive (by his own brother) in 27 AD and not dug up until 1901 – which menas he spent almost 1900 years in a cycle of  suffocating, dying and being reborn.  (Don’t try this at home, kids.)

5.  Did I say he can’t die?  that may otr may not be true any longer – after the events of the last series of episodes, Jack may or may not have reacquired his mortality.  (It’s complicated.)

6.  John Barrowman, who plays Captain Jack, has appeared on musicals in both London and New York and has recorded a number of CDs.  (One of those CDE’s includes a  song from Wicked that has been rewritten to be about Captain Jack.)

7.  He’s a bit of a slut.  (Why mince words about it?)  And I wouldn’t have him any other way.

8.  Barrowman and his sister Carole wrote an episode of a Torchwood comic strip (which has appeared in some issues of Torchwood Magazine.)  (Sounds like Barrowman & his sister have a better relationship than Captain Jack and his brother.)

9.  Jack has often had to make some extremely difficult “for the greater good” type of decisions – including at one time sacrificing his own grandson so that millions of others could live.  (And I have a hard time just trying to decide which movie I want to see!)

10.  AfterElton.com voted Captain Jack as one of the top 10 best gay or bisexual TV characters.
