Obviously, this is going to be one of the top Hollywood grossers in 2013. 'Gravity' starring George Clooney and Sandra Bullock had hit screens yesterday across the world. The results were thundering stunningly as it made a whopping collection of million dollars with few shows on the first day. Hollywood has made many 'Man Vs Nature' sci-fi thrillers that include 'Independence Day', 'Day after Tomorrow' and '2012', but this one seems to be outmatch all. Simultaneously released in 2D & 3D format, the spellbinding visual effects have stunned the audience. The story is about the survival of Matt Kowalsky (George Clooney), who is on his last expedition to space and the first space venture of Dr. Ryan Stone (played by Sandra Bullock), when a Debris hits the space craft and they keep floating in space without any communication to the world.
