這題是考關代的用法
依照題意，原句應為：
(1)Actor David Piper became tired of talking about the movie after he was interviewed about it many times.
(2)He is famous for the movie.
合併為：
Actor David Piper became tired of talking about the movie (which/that) he is famous for after he was interviewed about it many times.
關代為受詞時可省略，故答案為D
be famous for N. (此題的N. = the movie，但關代已經代替the movie 所以合併後的句子，就不用再寫一次了）
