MUMBAI: Early tracking soon after the release of the Robert Downey, Jr., Gwyneth Paltrow, Don Cheadle starrer Iron Man 2 suggests that the film might have the biggest opening weekend in history.

Iron Man 2 (IM2) that opened on Friday at a record 4,380 locations in North America will surpass the $102.1 opening of the original version two years ago. 

Reports say that IM2 grossed around $1.7 million at sold-out midnight screenings in North American with an additional $3.5 million from screenings that began as early as 8pm in New York on Friday.

IM2 began rolling out in Europe last weekend, where it has already sold more than $100 million worth of tickets.
