I believe the answer is:
actor
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">role player</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for actor that I've seen before include "One in a play" , "Person performing on stage or screen" , "one to take on roles" , "One on stage" , "Cruise maybe" .)
