Morgan: Streep is amazing as Maggie
Meryl Streep is "amazing" in her portrayal as Margaret Thatcher, the film's writer Abi Morgan has said.
The two-time Oscar winner takes the lead role as the former British Prime Minister in the upcoming biopic The Iron Lady, alongside Jim Broadbent as her screen husband Denis.
"It was amazing working with Meryl - once again, she's another dream actress, and a real privilege to write about such an extraordinary woman," Abi said.
"I'm really excited. They're laying the music down at the moment. I'm looking forward to seeing it."
Abi - who promoted her latest film Shame at the BFI London Film Festival - said it was "an exceptional privilege" to watch Meryl in the early stages.
"The extraordinary thing is how quickly that voice was there," she told the Guardian.
The Iron Lady, directed by Phyllida Lloyd, is scheduled for release in January 2012.
