There is nothing very new here,and indeed,it can be taken as a reprise of director Walter Hill's earlier and similarly themed movie "48 Hours"
Arnie plays a Soviet policeman sent to Chicago to bring back the Soviet Union's premiere drug dealer.He is "assisted",if that is indeed the appropriate word ,by a slobbish Chicago cop,played by James Belushi.Naturally it is not a routine assignment and much mayhem ensues before the predictable ending/The scenes in Russia are well staged and there is a chase sequence in Chicago,between two buses that makes a change from the more predictable cars.
Schwartzenneger is an under-appreciated comedic talent and his grim monosyllabic characterization is offset by Belushi's more fluid,and seemingly improvised style
The Soviets,or at least the Russians ,come out of this in a positive light (the villain is ,Arnie is at pains to point out a Georgian---interestingly so was the villified Stalin)I wonder if this is significant in securing Soviet co-operation in location shooting in Moscow.
There are some nice one-liners and the whole thing is diverting enough brain candy propelled along with the director's customary assured professionalism
