Query: English subtitles are not available on the main DVD.

The first thing you need to know is this is a Region 2 PAL DVD. I have a region-free DVD player so I could play it no problem but most DVD players in the U.S. will not play this movie.This is a first rate documentary of the racing career of Senna and I really enjoyed it. Interviews are recorded in the original languages (some are in English) and have subtitles available in Portugese and Italian. The second 'Extra Features' disk has English subtitles available. I didn't really see much there to watch.Enough of the interviews are in English so even without subtitles, I could follow much of the story and it is a great story.I have this movie in Blu-Ray also and bought this thinking it would add English subtitles so I could see what was missing from the Blu-Ray. The main feature is the same -- Portugese and Italian subtitles only.
