Yeah that's weird. When you search for "true grit" it finds the movie and John Wayne is correctly listed and one of the cast members. I'll sort it out when I get home, it's probably just a case of adjusting the querying algorithm. Thanks for letting me know.
I searched for [Steve Martin] and my sole result is "iSteve", which, as far as I can tell, doesn't have the token "Martin" in it at all. This is despite five Steve Martin films currently streaming on Netflix US.
