Sci-fi blockbuster Transformers has entered the North American box office chart at number one, with takings of $67.6m (£33.6m) in its first weekend.
The Transformers TV show and toys were hugely popular in the 1980s
The film has registered the highest first-week box office returns for a non-sequel in US cinema history, beating 2002's Spider-Man.
Transformers, about two races of rival robots who bring their battle to Earth, was also a popular 1980s TV series.
Robin Williams' new comedy License to Wed entered the chart at number four.
Last week's chart-topper Rataouille dipped to number two, with Bruce Willis' fourth outing in the Die Hard films dropping from number two to three.
Former box office leader Evan Almighty, psychological thriller 1408 and Michael Moore's Sicko, a documentary about the US healthcare system, all fell inside the top 10.
Pirates of the Caribbean: At World's End, which was released in May, broke the $300m (£149m) box office barrier, becoming the third film to make that amount this year after Spider-Man 3 and Shrek the Third.
But overall cinema takings fell 23% compared with the same weekend in 2006, which set a record of $135.6m (£67.4m).
