History / Film Research - Need info on Poland Martial Law period [9]

Hello and Thank you ! to anyone who clicks on this item. To be brief; I'm fulfiling a long past due commitment my friend and partner who passed away years ago and way too young. I am completing a screenplay we began, and the end of the final portion of the story occurs in 1981 Krakow. In order to be accurate in the film, I need to know what it was like to travel in / out / within Poland in the time martial law was imposed. As a westerner ( in Hollywood) , we imagine it was restrictive in nature, but I need to know some more details to have a good conclusion to the film. If anyone can point me to some good reference material, or ideally, contact with a person who could answer some questions it would be a fantastic blessing. - Regards, Bob

History / Early 80s - Could just anybody come stroling on in? [11]

Hi everyone - I'm trying to wrap up a screenplay and I would like to be as accurate as possible; I'd hate to be lucky enough to get it to film and then have Poles say " that's not how it was " . Specifically, under the communist governement at the time; could foreigners just fly in ?; was there a 'permit" required to enter; would Americans have an "escort" or be free to roam during those turbulent Solidarity years? This has a major impact on how i construct the conclusion, so any info is good info at this point !! ...thanks in advance
