i have been watching the 1st series of leverage on channel [virgin] one when the characters alternative id's were peter davison sylvester mccoy and tom baker anyone know the connection ?
apologies if this has been done before but i am not around a lot.

I don't know for sure, its interesting to see you post this, they do something similar on Supernatural, only they use names of famous rockstars, for instance in one episode the main characters used the names Page and Plant as alternative names while posing as FBI agents.

I've had a quick look on IMDB (not the most reliable source I know) to see if there was a connection, couldn't find one, so my guess is the writers are just DW fans

From IMDB trivia:

There are several references throughout the show "Leverage" to "Doctor Who" (2005).

In "Leverage" The Bank Shot Job (2008) Hardison expresses his frustration at the amount of time it took him to torrent the latest episode of "Doctor Who".

In "Leverage" The Mile High Job (2009), the aliases given are all references to "Doctor Who" (Nate's aliases, Peter Davison, Sylvester McCoy and Tom Baker, all portrayed The Doctor while Sophie's alias is Sarah Jane Baker, a reference to Sarah Jane Smith, one of The Doctor's companions).

Furthermore, in "Leverage" The 12-Step Job (2009), Nate again uses the alias Tom Baker, while Parker uses Rose, the name of another one of The Doctor's companions.

In "The Three-Card Monty Job," Hardison and Eliot assume the aliases "Detective Moffatt" and "Detective Davies," two of the executive producers and head writers of the new series.

thanks for that

Somebody on that show loves the Who.
