Top actors touring African country and missing a series of films (4,4)
I believe the answer is:
star wars
'a series of films' is the definition.
(Star Wars is a film series)
'top actors touring african country and missing' is the wordplay.
'top actors' becomes 'stars' (actors in starring roles).
'touring' indicates putting letters inside (touring can mean going round).
'african country' becomes 'rwanda' (country in Africa).
'missing' suggests deleting specific letters.
'stars' enclosing 'rwanda' is 'starwandars'.
'starwandars' with 'and' taken out is 'STAR WARS'.
(Other definitions for star wars that I've seen before include "George Lucas's cult sci-fi film" , "Strategic Defense Initiative (US) - sci-fi film" , "Movie" , "Space fiction film - SDI" , "Picture" .)
