CIRCLE THEATERS will host Seven From Greece, an offering of recent productions from that country, at their West End complex Friday through Thursday. The festival incorporates such highly touted films as Costas Ferris' Rembetiko and the Nikos Perakis comedy Of Colonels & Camouflage, which is sort of a political "Stripes" set on the eve of Greece's military dictatorship in 1967-1968.

Of particular interest is a 48-minute documentary on Greek-owned coffee shops in Manhattan, One on Every Corner, by local filmmakers Doreen Moses and Andrea Hull. It will screen before the scheduled feature this Sunday and Monday at 12:45. One cautionary note: even though the festival features two different films each day, they are not being sold as a double feature: The theater will be cleared after each show and separate admissions charged. Call 331-7471 for more details.
