"Avengers: Infinity War" shattered box office records as it crossed the $1 billion in sales mark in just 11 days, reports CNN citing Disney, adding that the Marvel film "reached the milestone one day earlier than the previous record held by 2015's "Star Wars: The Force Awakens."

"Infinity Wars" has surpassed the total sales of other comic book sensations including "Wonder Woman," "Batman v Superman: Dawn of Justice," "Guardians of the Galaxy," "X-Men: Days of Future Past" and "Justice League."
