John Robinson (11 November, 1908 – 6 March, 1979) was an English actor, who was particularly active in the theatre. Mostly cast in minor and supporting roles in film and television, he is best remembered for being the second actor to play the famous television science-fiction role of Professor Bernard Quatermass, in the 1955 BBC Television serial "Quatermass II".
John Robinson was 70 years old when he died.
This is true, because based on the dates given in the paragraph he wouldve been 70 years old. I think the system has a hard time understanding birth and death dates.
