I'm eagerly awaiting the Senna debut on a wider scale in the U.S. - apparently coming this July. However, Top Gear did a great job summing up Ayrton Senna's career in a nearly 20 minute segment from a season or two ago. I happened to watch it again this morning and it gets me excited for the full film on his racing career.
In case you haven't watched this yet - check it out now. Then I won't be alone in waiting in agony to see the full film!
