At the same time, it is reported that Christopher Eccleston has been cast as Amelia Earhart's co-pilot in an upcoming film based on the ill-fated aviatrix's life, while John Barrowman makes Canadian headlines when he's named a judge for the talent contest series How Do You Solve a Problem Like Maria? for the CBC.

It is known that he is to appear in the 2008 Christmas special as photos of him shooting the special had leaked to the press months previous.
 * 28 - DW:The Stolen Earth first broadcast. This historic episode marks the first three-way crossover between Doctor Who, Torchwood and The Sarah Jane Adventures.

Like the previous season finales, the broadcast of Journey's End sparks a frenzy of Internet discussion, both pro and con. The episode features the greatest concentration of active companions (as opposed to illusions and images) in the series' history (not including the non-canonical Dimensions in Time). The episode is viewed by 10.57 million people and becomes the No. 1 program for the week -- the first time this has occurred for any episode in the 45-year history of Doctor Who -- despite competition from the Wimbledon finals; it also repeats the previous week's feat and scores an Appreciation Index figure of 91, again unheard of for both Doctor Who and for a mainstream television production..

Julie Gardner confirms in the article that Tennant has made his decision as to whether he'll be staying on for the 2010 season, but she confirms that he will appear in all of the special episodes scheduled for 2009. Despite this, wildcat Internet rumours persist that Morrissey will replace Tennant as early as the 2008 Christmas special.
 * 12 - Doctor Who sweeps the television categories at the second annual Constellation Awards, a Canadian award presented as part of the Polaris science fiction convention.

This is a tie-in with the ending of DW: Turn Left.
 * 27 - The first Doctor Who Proms concert is held at Royal Albert Hall in London, featuring music from Doctor Who.
