Can anyone tell me if I need to watch the movie first before I watch FMA Brotherhood?

FMA Brotherhood is just the remake of the 2003 FMA. anda don't need to watch the movie first. If anda want to though; go for it!

Just to clear up, FMA: Brotherhood is lebih like an original since it faithfully sticks to the story in the manga. The 2003 version deviated from the Manga after a few episodes. So there's no link that stops anda from watching Brotherhood atau the movie in any order anda like :)
