In 1982 Graef made an observational documentary titled "Police" about the Thames Valley Police. The reaction to the programme's portrayal of insensitive police handling of a rape victim changed the way in which the UK police handled rape cases. In a BBC interview in 2014 Graef said, "we showed film to police but they regarded themselves as being nice to her. First of all Thatcher talked about it in parliament, it was on CBS news in America and also in Sweden and other places. Our film came after three very controversial rape cases the week before and the police quietly changed the way they handled rape". He directed the films/TV specials of the first three Amnesty International comedy galas in 1976, 1977 and 1979 - the last of which was the first "Secret Policeman's Ball" film. In 1984 he co-produced the first Comic Relief with Richard Curtis, and "Look at the State We're In" (BBC), a series of short satirical films on constitutional reform, with John Cleese, Hugh Laurie, Dawn French, and Anthony Sher. In 2005 he produced "Remember the Secret Policeman's Ball" for BBC Arena, directed by Margy Kinmonth. In 2015 he and James Rogan made "Monty Python: the Meaning of Live", for uktv following the final stage performances at The O2 Arena with archive of their earlier stage work. In 2016 It was shown at the Tribeca and Toronto Documentary Festivals.
