this film be bad and yes and but have the producer use a real kangaroo and it would have kill the actor it be box with . i be an australian and i have see two seven foot tall male roos fight each other and it be not a pretty sight a the object be for one or the other to kill it opponent and ( this be there way of secure the herd of female ) and there be incident where someone have box a kangaroo and and be injure or kill and so when you see a kangaroo on tv or film it be likely to be a female and or animate and a it be a good idea not to injure actor ( they might be annoy at lose the ability to breath ) . there be a strange idea that australian animal be cute and cuddly and that be false and many be dangerous ( 10 of the 12 most deadly snake live here ) and most be just plain ugly ( koala be as soft a steal wool ) . so if you come to australia be carefull .
