How can I play this movie?

I downloaded Hancock, but I get these files, I tried to join them with HJsplit but that doesn’t work either…

Anyone knows how to solve this?
*EDIT*: These are all the parts, yes.
Answer #1
Have you tried extracting them with WinRAR?
Answer #2
rename all the files to : Hancock.part1.rar
Hancock.part2.rar
Hancock.part3.rar
etc .. and than extract with winrar.
Answer #3
you can just open them with winrar, no need to rename
