Sidney Sedin
Julianne Nicholson did not play in Snatch, despite what IMDB and
Wikipedia says. In the 4th draft of the script from 1999, there are
two ladies in the bookies, one of which is named as "Pauline". In
the movie there is only one lady at the bookies and in the credits
"Pauline" is credited to Sidney Sedin. Julianne Nicholson does not
feature in the credits.
Plus, the lady in the movie does not look like Julianne
Nicholson. ;)
