To quote in part:
"WHEN JODIE FOSTER tried to eavesdrop on our
far-out friends in “Contact,” she simply sat on the hood of
her sports car and donned a pair of earphones.
"Charlie Sheen’s efforts in “The Arrival” were only slightly more
complicated. He first co-opted local TV addicts by
surreptitiously wiring their backyard satellite dishes to form
an ersatz SETI telescope. After that, it was easy. Sheen sat
back, drummed his fingers, and waited for alien signals to
light up his oscilloscope."
