Edna Jeffries, 74 from Easton in Bristol, humorously lost her life yesterday as a taxi driver whom she flagged down mistook her for a cast member of Bristol based drama Casualty.
She had suffered a heart attack and flagged down cab driver Dave Smith.
Mr Smith 55, from Stoke Bishop, thought she was actor Derek Thompson, who plays Charlie in the Medical drama.
Mr Smith was said to have laughed at Mrs Jeffries's antics and asked for an autograph.
When he realised that it was not Derek Thompson he apologised but it was too late.
Mrs Jeffries died by the roadside.
The BBC had no comment.
