I remember watching this when I was 11 in the 70's and thought it was funny, which some of it still is but some parts not so much. David Jason plays hapless (and to be honest irritating at times) spy Edgar Briggs who seems to get on despite being useless. Some fine supporting roles and you can see why Jason got the Del Boy role and also the roots of Johnny English, although both were much better. I can see why Jason blocked the repeats as it's not his best work but it's worth a look.
