The teasers in the universe of Doctor Who continue to come out. With Series 6 only three weeks ago, and following the official BBC trailer release the other day, BBC America has posted a trailer for the American broadcast including additional footage. On top of that, also in the Whoniverse, Starz USA has also released their teaser trailer for Torchwood: Miracle Day. You can see both trailers at the bottom of this post.

2011 is a big year for Doctor Who fans, with Series 6 premiering with opening episode The Impossible Astronaut on April 23. Matt Smith, Karen Gillan, Arthur Darvill, and Alex Kingston reprise their roles in the series, performing in stories penned by Steven Moffat, Neil Gaiman, Mark Gatiss, and more. This year is the first time a Doctor Who season will be split into two portions; with the first half playing during Spring, and the second following in Fall.

In between the two, during the Summer, Torchwood: Miracle Day will be premiering on both Starz USA and BBC UK on July 8. John Barrowman and Eve Myles reprise their roles in the series, joining up with new cast members as the Torchwood team find themselves in an adventure spanning the globe from Cardiff to Los Angeles.

Also later in the year, The Sarah Jane Adventures will be returning with the wonderful Elisabeth Sladen back in the title role for the fifth season of the show.

In the meantime however, check out the two new teasers below:
