Stars from TVs Brookside and Hollyoaks were due to join an anti-rape street march in Merseyside on Saturday.
Organised by the Wirral-based Rape and Sexual Abuse Centre, the "Reclaim the Night" procession was scheduled to take place in Birkenhead.
The aim of the march is to demand women's rights to feel safe walking on the streets at night.
It will end with the laying of roses at a memorial built to commemorate the life a pub worker who was murdered on her way home in 1986.
The sexual abuse centre is the only one of its kind in the North West region, and covers Lancashire and north Wales, as well as Merseyside.
After growing out of a small group meeting in a founder's kitchen, the centre handles more than 150 phone calls and at least 70 counselling sessions a month.
It also survived the threat that it might have to close its doors in 2002.
The march was due to start at 1800 GMT, from Birkenhead Town Hall, and will end with remembering Dianne Sindall, who was killed on her way home from the pub in Bebington.
