Sometimes we do not know who did an action or it is not relevant. Then, the subject can be "PEOPLE" or "THEY" with an active verb:
a) People say that these actors are handsome.
b) They say that these actors are handsome.
We can also use two types of impersonal passive:
a) It is said that they are handsome.
b) They are said to be handsome.
We can also use two types of impersonal passive:
a) It is said that they are handsome.
b) They are said to be handsome.
Pay attention to this examples in the past:
They knew she had an idea.
It was known that she had an idea.
She was known to have had an idea. (to + have V3)
If the predicate of the passive sentence is a verb transitive like believe, think, find, say, report, consider, understand, acknowledge, expect, tell, know then you can change the active sentence into passive. These are formal structures. They are often used in news reports and on TV.
