The character says his dog is "exactly" like Anwar Sadat
A film character's dog named after late Egyptian President Anwar Sadat has led to a court case being filed by a lawyer for one of Mr Sadat's daughters.
A character in I Love You Man says he named his dog Anwar Sadat because he looks "exactly" like the former leader.
The lawyer, Samir Sabri, has demanded an inquiry into the showing of the film and asked the US embassy for an apology, Masrawy website reports.
Several Egyptian bloggers say the film is an insult to their country.
The character, played by Jason Segel, says his dog is a cross between a beagle and a pug and is "the most beautiful dog in the world".
He says it is called "Anwar Sadat: after Anwar Sadat, the former president of Egypt".
When asked by his co-star, Paul Rudd, whether this is because he admires Mr Sadat's policies, he replies: "No, because they look exactly alike" and the film cuts to a shot of the dog.
A later scene shows the character also has a poster of Mr Sadat on the wall of his home.
Several Egyptian bloggers have complained about the film, which is currently showing in the country, saying it is insulting.
But others say it is an example of cultural differences between the US and Egypt.
Many Muslims regard dogs as unclean animals.
However, analysts say the film clip in question has not caused widespread offence in Egypt and it may have been edited out of the version distributed in the country.
Mr Sadat was assassinated in 1981 after he signed a peace treaty with Israel.
