Ross Kemp almost took a trip on the Oceangate submersible to film a documentary series.
The former EastEnders star was pulled out of it when the expert production company behind the programme said it was "not considered safe".
The US Coast Guard confirmed recently that five people were all killed onboard the OceanGate submersible Titan.

Days of desperate searching for Titan were launched after it lost contact with a surface vessel on Sunday, as search crews hoped it was simply stuck.
A "catastrophic implosion" is the likely cause of their deaths.
And now, it has been revealed that Ross, 58, was chosen to front a documentary that would require him to dive down in the submersible.
His agent, InterTalent boss Professor Jonathan Shalit, explained: “Their team checked out this OceanGate submersible and pulled out of using it, as it was simply not considered safe or fit for purpose.
“They found other sub dives which have been safe and successful, but by that point Ross was so busy with all his TV shows that he was unable to commit the time."
He added to The Sun that he was 'relieved' that he wasn't known as the "agent who killed Ross Kemp".
The five victims consisted of three British citizens including billionaire Hamish Harding. Shahzada Dawood and his son Suleman Dawood were also onboard along with French national and renowned diver Paul-Henri Nargeolet.
The confirmation of their deaths came after a debris field was found by the US Coast Guard during their search for the missing vessel.
Rear Admiral John Mauger, First Coast Guard District commander, said they had found debris linked to the Titan.
"The debris is consistent with a catastrophic loss of the pressure chamber," he said in a press conference.
A former Navy doctor has explained what would have happened to the five victims before they died.
Dr Dale Molé said: "It would have been so sudden, that they wouldn't even have known that there was a problem, or what happened to them."
