Haunted by terrible feedback from viewers and less-than-average reviews from analysts, "Fifty Shades of Grey" may not be enjoying a great reception critically. However, clearly more people than would like to openly admit, are lining up to see Sam Taylor Johnson's erotic movie.

The film, based on the best-selling book by British author EL James, has garnered $486.2 million worldwide so far with $50 million from the international box office collections this weekend alone, according to Rentrak's estimates.

Rentrak's senior media analyst, Paul Dergarabedian, calls "Fifty Shades of Grey" a "staggering worldwide phenomenon" with a global box office collection of $36 million and domestic collection of about $11 million.

The Jamie Dornan-Dakota Johnson starrer is closely followed by "Kingsman: Secret Service", with a worldwide box office collection of $37.5 million. The British espionage comedy starring Collin Firth earned $25.8 million internationally and $11.75 million in the US theatres.

And the con-man film "Focus" starring Will Smith and Margot Robbie of "The Wolf of Wall Street" fame, earned $31 million worldwide.

Meanwhile, "American Sniper", the biopic based on the life of the United States Navy SEAL Chris Kyle, became highest grossing Clint Eastwood directed film internationally, with a box office collection of $27.2 million worldwide. The film, which has Bradley Cooper in the titular role, earned $7.7 million in the US box office and $19.5 million globally.

There are no indications of "Fifty Shades of Gray" dropping from the top box office collections chart anytime soon, with Dergarabedian predicting that it would cross the $500 million mark later this week making it one of the most profitable films released over the past one year.
