Where can you watch full Thai movies legally?

Amazon Instant Video has a good selection of full-length Thai movies in various genres, uncut and commercial free. Many are Prime Eligible which means Amazon Prime members can stream them for free.

From Amazon.com, search “Thai movies” under Amazon Instant Video. As of 2015, most of the movies available are in standard definition with only a few in high definition. English subtitles are available for those who don’t understand Thai. The biggest selection is in the action-adventure category; however, there are several comedies, dramas and musicals as well. About one-third of the Thai movie listings are Prime Eligible. Non-Prime Members can rent or purchase movies.
