add a comma or semicolon if needed. otherwise, submit the text without any additional punctuation.\n\nwhen alfred hitchcock was making the movie the birds in the 1960s he borrowed a special camera from walt disney to film the infamous bird attack scene.
Answer
Explanation:
The sentence starts with a dependent clause ("When Alfred Hitchcock was making the movie The Birds in the 1960s") followed by an independent clause ("he borrowed a special camera from Walt Disney to film the infamous bird attack scene"). When a dependent clause comes before an independent clause, a comma is used to separate them. So we add a comma after "1960s".

When Alfred Hitchcock was making the movie The Birds in the 1960s, he borrowed a special camera from Walt Disney to film the infamous bird attack scene.
