Red giant, maybe, seen in movies? (4)
I believe the answer is:
star
'red giant maybe' is the definition.
(I know that red giant is a type of star)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for star that I've seen before include "Main attraction" , "Point of light in the heavens" , "Principal actor in a film" , "Shiner" , "Famous player" .)
