It is clear that absolute does not modify movie - it is not an "absolute movie". Instead, absolute modifies favorite, so it is an adverb, and should be written as "absolutely".This is confusing me, which one is correct:
- My absolute favorite movie of all time.
- My absolutely favorite movie of all time.
There are actually four examples in the COCA corpus of absolutely favorite, all followed by a noun.The fact remains that I can find no case in either the British or the American Corpus of absolutely favorite + noun, but there are a few of absolute favorite + noun, which is the form of words I've always heard. Look at the ngrams.
If you don't want it to sound strange, Ucul, say absolute favorite movie.
