(1) May I suggest that your sentence is: He was also one of the few actors WHO I thought were crazy.
(a) In this case, "I thought" is strictly parenthetical. Erase it from your mind when you are analyzing the sentence.
(b) Thus we have: He was one of the few actors who were crazy.
(i) My books tell me that the verb is "were" because it matches "who" which refers to actorS, not to "one."
(c) In other words: He was one. One of what? Of the few actors who were crazy.
(2) Don't be surprised, however, if you hear native speakers use "was."
(3) "Was" WOULD be correct if the sentence read: He was the ONLY one of the actors who was crazy. Just erase the words "of the actors" in your mind, and you can see that the sentence reads: He was the only one who WAS crazy. (The other actors were not crazy.)
Have a nice day.
