Uma Thurman has a flighty way of keeping her physique in top shape - the actress practises dance moves and yoga poses when travelling by aeroplane.
The 38-year-old Kill Bill star unbuckled her seat belt and started stretching during a flight from New York to Salt Lake City, Utah, where she will appear at the Sundance Film Festival this weekend (beg17Jan09).
A witness tells the New York Post, "She used the flight-attendant station as a ballet barre, where she stretched and did plies for 20 minutes."
But the in-flight antics were the end of Thurman's health-consciousness, according to the onlooker: "After we left the plane, she ran for an exit and then chain-smoked like crazy."
