i have always be a great admirer of nicolas roeg and walkabout be one of my favorite film . this be a film version of roegs stage play and while most of the film take place in a hotel room it still have some of roegs cinematic flare . very unique story be about a famous actress ( theresa russell ) who after a hard night work on a film in 1954 go to a hotel to visit a famous professor ( michael emil ) and together in his hotel room they talk . after awhile she want to go to bed with him but a they start to get undressed her husband be bang on the door . her husband be a famous ex baseball player ( gary busey ) and he want to know what be go on . the three of them in the hotel room talk about what be go on and what the future hold for them . meanwhile and a famous senator ( tony curtis ) be threaten to take away the professor paper if he doesn not testify at a hearing . theresa russell be just excellent and while she not try exactly to impersonate marilyn monroe she do a wonderful job of exude the phobia and nuance that monroe be very well know for . one thing the film do be show her a not only a woman on the verge of a mental breakdown but show her a a physical wreck as well . she talk of be unable to have child and at one point in the film she suffer a miscarriage . you can make an excellent case that this be russell best performance and i probably wouldn not argue . the film do an interesting thing in show many flashback a the character continue to talk about one thing and in the flashback we see one of many reason for their action . busey also give a good solid performance and it remind me of what a strong persona he give off on screen . emil a the professor be a character that have many more thing on his mind then we originally think . the last scene in this film be a demonstration of his darker side . one of the highlight of the film for me be the little conversation he have with the elevator man ( will sampson of cuckoo nest ) and they discuss what cherokee indian think about at all time . but of course the famous scene in this film be where russell demonstrate to emil how she do understand the theory of relativity and use toy to show this . the professor be delight by her demonstration and so be we . russell and roeg be marry in real life and they do admirable work when they be in collaboration and this be probably their best film together . good performance and a very interesting job of direct make this a challenging and visually think provoke film .
