To be specific, HDMI doesn't support traditional closed captioning which is embedded in the NTSC/PAL video signal (an unfortunate oversight on the part of whoever designed the HDMI and Blu Ray standard), but many DVD and Blu Ray discs do offer subtitles which are generated by the DVD player itself and superimposed on the screen, and indeed, the product details listed at Amazon.com say that the Star Wars Blu Ray set offers English subtitles (as well as French, Portuguese, and Spanish).
