Hollywood actor Robert Pattinson is worried about the fate of his upcoming film 'Remember Me' as it isn't the 'happy romantic drama' audiences may be expecting.

'It does worry me that when a film has a lot of attention, most audiences are used to having all their buttons pressed, and it doesn't really press the same buttons as other films,' imdb.com quoted him as saying.

'I hope people don't go into it thinking, 'I am going to watch a really happy romantic drama', because it is not really,' Pattinson said.
