" is on top of the nation's box office derby for the third straight week, and is now the highest-grossing movie in Walt Disney Studios history.
The action heroes flick is estimated to take in $55 million this weekend in the U.S. and Canada, and has amassed a massive $457 million in domestic receipts.
Only "Avatar" had a better third weekend, and "The Avengers" has just moved ahead of "Spider-Man" in that regard, said movie industry analyst Paul Dergerabedian at Hollywood.com.
Three movies debuted in the top five this weekend, including "Battleship" in the number two slot, with a $25.4 million domestic take.
Like "The Avengers," "Battleship" was opened overseas early, and it is crossing the $250 million mark worldwide this weekend, according to estimates from Universal.
Sasha Baron Cohen's "The Dictator" opened with a $17.4 million splash, good enough for third place. Dergerabedian called that "a better-than- expected debut."
In its second week of exhibition, "Dark Shadows" crossed the $50 million mark with a $17.4 million haul this weekend.
And a movie aimed squarely at the "date market" -- according to Dergerabedian -- opened in fifth place. "What To Expect When You Are Expecting" got a $10.5 million gross.
The remaining 10 most-popular movies in North America this weekend, as evidenced by studio estimates that are collected by Hollywood.com, are "The Best Exotic Marigold Hotel" ($3.3 million), "The Hunger Games" ($3 million), "Think Like A Man" ($2.7 million), "The Lucky One" ($1.8 million) and "The Pirates! Band Of Misfits" ($1.5 million).
