Colin Firth filming in Lower Marsh

The star has been making Trauma, a Warner film due for release late next year, which tells the story of a man who struggles to overcome the death of his partner.

The Waterloo market was transformed for the three days of filming with extra stalls on both sides of the street and shops restocked for filming.

The film company has paid £4000 to the traders to fund promoting the market which has recently suffered a loss in customer numbers following further office closures. Lower Marsh has also been promised a mention in the credits.
