我5月3号看了这部电影。翻译成英文

I saw this film on May 3rd.

一般过去时:I watched this movie on May 3th.
现在完成时:I have watched this movie on May 3th.(但现在完成时..不可加时间..所以该句不成立)
正确应为"I watched this movie on May 3th.

I watched this movie on March 3rd.

I have watched this movie on May 3th.

I watched this movie on May 3rd

I saw the movie/film on May 3th.
