I have indeed heard of Nicolas Roeg's Walkabout. This film has been screened several times at USC as part of an introductory graduate theory caXXX class. You m XXXX may want to contact the Norris Theater staff at USC for info on its distribution as they have rented it in the past. Try contacting the Critical Studies office at USC at (213) 740-3334. They should be able to transfer you to the correct phone number at Norris Theater (you shouyXXX should probably speak to Dana who is in charge of operations there). Best of luck.
