Hollywood film-makers urge Iran to release Jafar Panahi
Hollywood film-makers including Steven Spielberg and Martin Scorsese have called on the Iranian government to release director Jafar Panahi, BBC reported.
A petition also signed by Robert De Niro, Robert Redford and Francis Ford Coppola, denounced the arrest of Panahi on 1 March.
"We... stand in solidarity with a fellow film-maker", the petition read.
Panahi, known for his social realism, has made several films critical of Iran's regime.
The group of film-makers and actors "strongly urge the Iranian government to release Mr Panahi immediately", the petition continued.
Plain clothes police broke into Panahi's family home and arrested him, his wife and daughter and 15 other guests, his son Panah told reporters last month.
The Tehran prosecutor's office has confirmed the arrest to reporters but denied it was connected to politics.
"The arrest of Jafar Panahi is not because he is an artist or for political reason," prosecutor Abbas Jafari Dolatabadi told the Isna news agency.
"He is accused of some crimes and was arrested with another person following an order by a judge."
Last year a travel ban was imposed on Panahi by the authorities after he appeared wearing green - the colour of opposition supporters - at the Montreal film festival.
He was also briefly arrested after attending a memorial to student Neda Agha Soltan, killed at an opposition rally last June.
Panahi is a past winner of the Venice Film Festival's Golden Lion award.
His most recent film is Offside, which won the 2006 Berlin Film Festival's Silver Bear award.
It tells the story of a group of female football fans who try to sneak into Iran's World Cup qualifying match against Bahrain but are arrested.
In Iran, women are banned from attending men's sporting events.
At least 30 protesters have been killed in clashes since last year's disputed elections, although the opposition says more than 70 have died. Thousands have been detained and some 200 activists remain behind bars.
At least nine have been sentenced to death, and two have been executed already.
Some of those arrested include former ministers and the sister of Nobel laureate Shirin Ebadi.
