This was part of a campaign to teach 1 million UK adults to read during the 1970's and Bob Hoskins played a character that needed encouragement to learn to read. This was the first time that Bob Hoskins came to my attention on a British TV programme that appeared to be a 'Sesame Street' for adults. Soon after he had the lead role in 'Pennies from Heaven' and his career took off.
If anything this series showed that the skills of an actor are not just for entertaining but can be educational and inspirational. And if people followed Bob Hoskins characters example and learnt to read, then it must count as one of his most successful jobs in his long career.
