Bruce Lee hardly talks in this

At roughly the halfway point, he says to O'Hara "Boards don't hit back", and that's his last bit of dialogue until the climax of the movie when he says to Han "You have offended my family, and you have offended the shaolin temple".

I'm not complaining. Bruce Lee had the screen presence and charisma to pull it off. It was just something I only noticed the last time I watched it. When I think of taciturn film characters I think of people like Mel Gibson in The Road Warrior, I didn't realise about Lee in this.
