Actor Dennis Hopper has taken ill during a publicity trip to New York, according to his publicist.

Sheila Feren said that the 73-year-old star of “Easy Rider” and “Blue Velvet” was being examined at an unidentified New York hospital Wednesday afternoon after developing flulike symptoms earlier in the day.

In town to publicize his current TV series, “Crash,” he was forced to cancel a number of interviews and TV appearances.
