你看没看过那部叫回到未来的电影？翻译成英文

以上全错
seen应该是watched.

film也不能说错，不过没听过,通常说movie.

若你不知道他有没有看过.
Have you ever watched a movie called "come back to future" ?

若你认为他很可能看过.have you ever watched "come back to future" ?

t2lcx,你有听过人说see a movie么？
在goolge上搜索一下see a movie和watch a movie.
see a movie是很特殊的用法, 用于这个never wanted to see it是对的, 但若要说看过就要用my friends all watched it.
上面说的went to see with sister,这个地方显然表达他没有看完这个电影.

你看没看过那部叫回到未来的电影？
Have you ever seen the film named "Back to the Future"?

回楼上的
watch只是强调过程
一般用的多的还是see
这是一个老外写的原话：One of the last movies I went with sister to see back in 86. The film blew my mind. My friends never wanted to see this one.

还有 英语中电影名是不加双引号的

这样说比较恰当：
Have you ever seen the movie called Back To The Future？

Have you ever seen the film called “Back to the Future”?
电影名是译为这样的。

have you ever seen the film called "come back to future"
