Synch 'Christmas Around the Corner' is set in a bookshop (Vermont ,as usual
). It's the only one that comes to mind off the top off my head, but there must be more.
I don't have the Hallmark channel itself- but on Virgin/Freewiew the GRT!XMAS movies channel shows the hallmark/hallmark style movies. Also, Movies 24, which becomes a Christmas channel from October -January 2nd ish. It's hard to tell if they show them all- they get repeated so often, and have been going a while. There do seem to be a lot more from th last 2/3 years than normal though.
As for 'recognisable'- it really depends on your idea of 'famous'. Don't be expecting to spot
Meryl Streep
. So, yes, Mariah Carey turned up in one, and actors such as Melissa Joan Hart, Haylie Duff, Rupert Penry Jones was in 'Crown for Christmas'- but 'well known' is more 'well known' in the genre- Candace Cameron Bure (Well known in the US for Full/Fuller House) has cornered the market- and is in lots of them. LAcey Chabert (Party of Five) is as well. Toni Braxton has turned up in a couple, and Kristin Davis (Sex and the City) has been in a few.
But it depends on who you mean by 'well known'.
I never really recognise as many of the blokes- they all kind of merge into one
though the bloke who was Bailey on 'Party of 5 ' is in one with Kristin Chenoweth.
