Sir Michael Caine is reportedly planning to take legal action against Marsh & Parson’s after the London-based estate agency, owned by LSL, used his image and a reference to a classic line in one of his films to advertise its business – without his consent.

The actor was unhappy to learn that Marsh & Parsons had used his portrait on a poster in the window of its branch in Kensington, West London.

The advert featured a picture of the Hollywood star, 89, with a quote of his famous line in The Italian Job: “You were only supposed to blow the ****** doors off!”

It is not the first time one of Marsh & Parsons’ adverts which juxtapose descriptions of property with images of people has got them in trouble.

The agency was forced to remove an outdoor advert featuring the now former prime minister Theresa May, again without her permission.

According to the Daily Mail, Caine’s team were furious after learning that the property firm was attempting to cash in on their client’s fame.

It is understood that the news prompted his Los Angeles agent to send emails with the words ‘without his permission’ written in capitals.

Marsh & Parsons has been approached for comment.
