Actually a circular polarizer comprises two thin plates glued together: a linear polarizer and a quarter-wave plate (whose optic axis is aligned at 45 deg to that of the linear polarizer).

Hmm? A linear pol. filter still has the film sandwiched between 2 glass plates. Does not matter that a circular one adds something extra... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/cool.gif' class='bbc_emoticon' alt='Smile' />
