Ross Kemp turned down a trip to see the Titanic on an OceanGate submersible for a TV show over safety fears.
The documentary-maker and former EastEnders star had been keen to take part in the mission last year but it was deemed to be unsafe. An expert production company carried out checks and decided it would be too risky to let anybody board the Titan submersible to view the shipwreck on the seafloor of the North Atlantic, off the coast of Canada.
Kemp's agent, InterTalent chairman Professor Jonathan Shalit, said they pulled out of using the OceanGate craft because it was deemed to be unsafe "on every level". Prof Shalit told the PA news agency: "The production company, who are well known and renowned, looked into the sub and decided it was unsafe on every level and weren't prepared to use it.
