Hello Ion,
Your best bet would be the National Film Archive, which you can reach at:
Tel: +40 (21) 313 4904
Fax: +40 (21) 313 0483
They can search through their records for a specific film, provided you give them enough info. The only problem would be that I am not exactly sure how many of them speak proper English. I am afraid it might not be enough to exchange faxes or phones, it might be necessary to come in person here.
However, if those films were made for TV, and not for cinema (you didn't specify), there is also a chance that they are at the Romanian Television Archive:
Tel: +40 (21) 230 7501
Fax: +40 (21) 230 0381
Email:

Since they deal on a regular basis with foreigners, you will find English-speaking personnel there. However, they do charge for access to their archive, so you will need to come up with a good reason as to why you need those films.
Cheers,
Andrei
P.S. I hope the phones for the ANF are current, to the best of my knowledge they are. If you are having problems getting in touch with them, let me know and I'll try to find out if they changed.
