Forty miles east of Dallas, the neon lights outside the old Majestic Theater will go on (nightly except Wednesday), owner Karl Lybrand III will fire up the popcorn machine, then take his place in the ticket booth. The 300 seats inside won't be filled, but there will be anywhere from 15 to 50 faithful patrons forking over $2 for a ticket to see a movie that showed in one of the big city's multiplexes a month earlier. The place is as fun and romantic as first love. One of only 100 single-screen theaters still in business in the United States, it is the oldest family-owned movie house in the country. The senior Lybrand first showed movies to Wills Point patrons in 1907. Doors open nightly at 7 p.m., and the feature will be shown only once. Don't be late, or you'll miss the previews.
