British actor Michael Jayston (seen in the above photo) portrays James Bond.
As CommanderBond.net notes, the radio adaptation is faithful to Ian Fleming's novel, unlike the 1967 film adaptation.
The film was silly, but I loved Sean Connery as Bond, I loved John Barry's musical score, and of course I loved the beautiful Japanese girls. I wished that the filmmakers had followed the novel rather than substitute it with an original story.
I heard the broadcast when it originally aired on BBC Radio and I liked it. I thought Michael Jayston was convincing as James Bond.
At one point Jayston was in the running to portray Bond in one of the films. I like Jayston in the miniseries Tinker, Tailor, Soldier, Spy, and when I was stationed in Scotland with the Navy in the early 1970s I used to regularly watch Jayston on TV in a very good spy thriller series called Quiller.
