He made two films immediately after the series ended: Crossplot (1969), a lightweight 'spy caper' movie, and the more challenging The Man Who Haunted Himself (1970).
Directed by Basil Dearden, it gave Moore the opportunity to demonstrate greater versatility than the role of Simon Templar had allowed.
In 2004, Moore said of The Man Who Haunted Himself: "It was one of the few times I was allowed to act... Many say my best role was in The Man Who Haunted Himself.
Being a modest actor, I won't disagree."

Lew Grade lured Moore to star alongside Tony Curtis in The Persuaders!.
The show featured the adventures of two millionaire playboys across Europe.
Moore was paid the then-unheard-of sum of £1 million for a single series, making him the highest-paid television actor in the world.
Lew Grade claimed in his autobiography Still Dancing, that Moore and Curtis "didn't hit it off all that well".
Curtis refused to spend more time on set than was strictly necessary, while Moore was always willing to work overtime.

According to the DVD commentary, neither Roger Moore, an uncredited co-producer, nor Robert S. Baker, the credited producer, ever had a contract other than a handshake with Lew Grade.
They produced the entire 24 episodes without a single written word guaranteeing that they would ever be paid.

The series failed in the United States, where it had been sold to ABC, which Curtis put down to its showing at the Saturday 10pm slot, but it was successful in Europe and Australia.
In Germany, where the series was aired under the name Die Zwei ("The Two"), it became a hit through especially amusing dubbing which only barely used translations of the original dialogue.
It was also popular in Britain, although on its premiere on the ITV network, it was beaten in the ratings by repeats of Monty Python's Flying Circus on BBC One.
Channel 4 repeated The Persuaders!
in 1995.
Since then the series has been issued on DVD, while in France, where the series (entitled Amicalement Vôtre – "Yours Sincerely") had always been popular, the DVD releases accompanied a monthly magazine of the same name.
