Film shown in Bratislava: Tarzan (6)
I believe the answer is:
avatar
'film' is the definition.
(I've seen this before)
'in bratislava tarzan' is the wordplay.
'in' says the answer is hidden in the clue.
'AVATAR' is hidden in the letters of 'bratislava tarzan'.
'shown' is the link.
(Other definitions for avatar that I've seen before include "Online image" , "Incarnation of a Hindu god" , "Visual manifestation of something abstract" , "Graphic" , "Cyberspace person's image" .)
