The 68-year-old Call The Midwife star will be joined by Sheridan Smith and Sir Tom Courtenay, 84, for The Railway Children Return, due out in April. Released in 1970, the original film told the story of a mother and her three children who move to Yorkshire in 1905 after their father was wrongly incarcerated.
The movie also starred Dinah Sheridan, Bernard Cribbins, Sally Thomsett and Gary Warren. Jenny was a teenager when she rose to fame as the eldest of the kids, who stopped a steam train from hitting an injured boy by swinging her red petticoats.
The new film will be shot in key locations from the original film, including Oakworth Station in Haworth, West Yorkshire, and nearby Bronte Parsonage.

The sequel features a new generation of child stars who are evacuated to a Yorkshire village during World War II, where they encounter a soldier far from home.
