The film “Zack and Miri Make a Porno”, starring Seth Rogen and Elizabeth Banks, was advertised by Entertainment Film Distributors on posters on the side of buses.

Many complainants were concerned with the use of the word “porno” in the title, and the fact that the poster could be seen by young children, who may then ask what it meant.

The ASA, however, said the ad did not contain any explicit imagery, and did not in itself breach any rules.

The ASA said: “We did not consider that the ad would cause widespread or serious offence or harm to children.”

Complaints not investigated.
