Lily Tomlin is a class act, on or off the screen, on or off the stage. Her one-woman show, ''The Search for Signs of Intelligent Life in the Universe,'' which she did on the stage, has now been put to film, one that is now showing at the Senator.
Tomlin makes you work. Her comedy is more fey than obvious. You do have to listen, but if you do, the pleasure is immeasurable.
As she did on stage, Tomlin plays a variety of characters, a rebellious teen-ager, a bag lady, a '60s woman, a married woman, a mother, a divorced woman and a team of hookers, Brandy and Tina.
Because this is film, Tomlin is able to play both women in the same sequence, and while this doesn't necessarily add to the film, it doesn't take anything away, either.
At one point, through screen magic, Tomlin plays two characters at the same time, one male, the other female.
Observations by all these characters are worth hearing, even if the wit is occasionally thin.
Because this is film, Tomlin moves from character to character with psychedelic overlap. This, too, doesn't hurt.
Jane Wagner wrote all this material, and John Bailey directed the film. Tomlin fans are advised to attend.
