I would suggest you watch the extras on the Spaced, Shaun of the Dead and Hot Fuzz DVDs and, in particular, the commentaries on those disks as - from memory - there are quite a few references to their past experiences influencing various scenes in all three.
Past that, there may be more information on peggster.net
, if you are up for a trawl through those sites (I'm not sure there's much on here, but reading through the interviews
section and Edgar's Q & A page
may elicit some further information).
Good luck with your project!
