Re: Christian Bale v.s. Michael Keaton - Part 1
It almost impossible to compare the two for me...
Bale was given more attention script wise and had many more opportunities for genuine 'acting' moments. Or shall we say periods of reflection.
Keaton had Burton's visual flair guiding him... allowing him to look an intimidating and forceful figure on the screen. Also I think keeping his dialogue to a minimum allows him to have an overall greater presence.
It visual storytelling/ presence vs. sheer exposition for me.
