Los Angeles: Jennifer Lawrence says she came to admire Chris Pratt's "amazing attitude" while working with him on sci-fi drama 'Passengers'.

"Chris Pratt is the hardest working person on a movie including the crew, including ... I mean, he is the hardest working person I've ever met in my life and has such an amazing attitude that I had to tell him to stop being so happy at like 4 in the morning. I was like, no, no, you need to be grumpy," Lawrence said about her co-star.

"Passengers", which is being released in India tomorrow by Sony Pictures Entertainment, is about two strangers Jim and Aurora, who are on a 120-year journey to another planet on technologically- advanced 'cruise-liner' style space ship when their hibernation pods wake them 90 years too early.

Lawrence, 26, also thinks that Pratt is a better dancer than her but she is confident that she "could get around him easier" when it came to basketball.

Asked what attracted her to the story, the Oscar-winning actress says she loved the world (created in the movie).

"I loved the characters and I loved just the sheer idea of the whole thing. I thought it was so creative and interesting and I hope people will walk out of the theater with a million different opinions and that's what I really liked about the film is that nobody's telling you how to fall. It's, what would you do? It's a conversation starter."

Her character Aurora is planning on being the first person to ever travel to the new colony world, and take a 120-year journey and then 120 years back, and she wants to be the first person to make that journey and write about it.
