To be honest with you, I get a little fed up with actors who act crazy to make themselves more interesting.
Carrying out the thing, getting it to the point when one might say: There, now it is good - that point is hard to reach. Often, one sets very high goals for oneself. Perhaps too high.
You want to do something that shows some type individuality and talent and imagination - at the same time, you want to be truthful to the predecessors, because obviously the audience liked something about them and you have to replicate that experience to a certain extent.
