Bless my bunions."" What have we here-- it's One of Dylan Thomas' film scripts -- a stormy opera bouffe about mid-19th century Wales. One night, when the wind is ""ripping and wailing,"" young Anthony Raine returns from India to the hot milk and senna pods of his faithful housekeeper, to pretty Rhiannon, and to the night riding insurgents known as Rebecca's daughters who are protesting against the tollgates and, as in the Bible, determined to ""possess the gates."" While the script itself is not much more than a long short (a liability the book-- as a novel-- will face) still there's a lavish swagger and a bonhomie which will recommend it to Thomas' admirers. Or as part of the collection of his complete works.
