In rails, activesupport there is the titlize method
# Capitalizes all the words and replaces some characters in the string to
create
# a nicer looking title. Titleize is meant for creating pretty output. It is
not
# used in the Rails internals.
#
# titleize is also aliased as as titlecase
#
# Examples
# "man from the boondocks".titleize #=> "Man From The Boondocks"
# "x-men: the last stand".titleize #=> "X Men: The Last Stand"
def titleize(word)
humanize(underscore(word)).gsub(/\b([a-z])/) { $1.capitalize }
end

So for your file you could use

File.open( '\movies.txt') do |f|
 f.each_line do |line|
  puts line.gsub(/\b(a-z])/){ $1.capitalize }
 end
end

Or if you don't mind printing the whole thing out in one go

File.open( \'movies.txt') do |f|
  puts f.read.gsub(/\b([a-z]/){ $1.capitalize }
end
