Remake of Godfather' s iffy? Yes, but it's a spanking tale (5,6,2,4)
I believe the answer is:
fifty shades of grey
'remake of godfather' s iffy? yes but it's a spanking tale' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'remake of godfather' s iffy? yes' is the wordplay.
'remake of' indicates anagramming the letters.
'godfather'+'s'+'iffy'+'yes'='godfathersiffyyes'
'godfathersiffyyes' with letters rearranged gives 'FIFTY SHADES OF GREY'.
Can you help me to learn more?
(Another definition for fifty shades of grey that I've seen is " 24's work".)
