Meryl Streep's latest movie The Iron Lady, a biopic on the UK's first female prime minister Margaret Thatcher, had a promising box office showing during its limited weekend release.

The Iron Lady has made approximately $280,409 since its limited debut on Dec. 30, according to Weinstein Co., the Los Angeles Times reported. It was played in two theaters in New York City and two in Los Angeles.

We couldn't be happier with the results, Weinstein distribution chief Erik Lomis told TheWrap. Obviously it's the number one screen average by a mile for the weekend.

The Iron Lady will have a wide U.S. release on Jan. 13. It hits UK theaters on Jan. 6. The film has already been released in Australia.

Previews have yielded mixed results, with many critics praising Streep's performance but questioning the script's portrayal of the former prime minister. The movie currently has a 58 percent rating on RottenTomatoes.com.

Thatcher's children are said to be less than thrilled with the results.

Sir Mark and Carol are appalled at what they have learnt about the film, a family friend reportedly told The Telegraph. They think it sounds like some Left-wing fantasy. They feel strongly about it, but will not speak publicly for fear of giving it more publicity.
