单选题 If he produced a sequel to his first successful film, the new movie would be a success ______ who plays the leading role.

A. the same as
B. far from
C. regardless of
D. even though

【正确答案】 C

【答案解析】[解析] 语法：介词 1．本题考查名词性从句。 A. I know who is John. B. We are talking about who is John 比较上面两个句子可以发现，名词性从句who is John可以作动词宾语，也可作介词宾语。 2．选择介词regardless of后，名词性从句“不管谁当主人公”切合原文，因此C为正确选项。
