He told the Radio Times she once confronted Brown – another of EastEnders’ biggest stars and who played Dot Cotton – after she criticised the writers.
“Barbara was the best executive producer EastEnders never had,” Treadwell-Collins said.
“She was so sharp, she knew the audience, and kept actors young and old in check. Once, June Brown shouted at us from her dressing room window, ‘Your storylines are shit.’ Barbara grabbed her, brought her upstairs and told her to apologise.”
Dame Barbara, who died after being diagnosed with dementia, also admonished Samantha Womack and Rita Simons.
