Liverpool player reportedly was crossing river for epic struggles (4,4)
I believe the answer is:
star wars
'epic struggles' is the definition.
(epic sci-fi films)
'liverpool player reportedly was crossing river for' is the wordplay.
'liverpool player' becomes 'Starr' (Ringo Starr - the Beatles were from Liverpool).
'reportedly' shows a homophone (sound like).
'crossing' indicates putting letters inside.
'river for' becomes 'r' (I am not sure about this - if you are sure you should believe this answer much more).
'starr' sounds like 'star'.
'was' enclosing 'r' is 'wars'.
'star'+'wars'='STAR WARS'
Can you help me to learn more?
(Other definitions for star wars that I've seen before include "Space fiction film - SDI" , "George Lucas's cult sci-fi film" , "Strategic Defense Initiative (US) - sci-fi film" , "SF film" , "Cult film - Reagan initiative" .)
