Alien robots have transformed into box-office superstars with $200 million in domestic ticket sales in just five days. Transformers: Revenge of the Fallen took in $112 million in the sequel's first weekend and $201.2m. since opening Wednesday in the US, according to Sunday estimates from Paramount, which is distributing the DreamWorks movie. It was well on the way to becoming the year's top-grossing movie. The estimate was a few million dollars higher than other studios were expecting for the movie. Now playing in almost every other country except India, the movie added $185.8m. overseas, for a worldwide total of $387m. That's well over half the $708m. global total for the first Transformers, which began with a $70.5 million weekend. For the first five days, the Transformers sequel was second only to last summer's The Dark Knight with $203.8m. It was the biggest opening weekend of this year, surpassing the $85.1m. debut of X-Men Origins: Wolverine in early May.
