Wont be done. Too much work. That is why FFVII wont be remade for the PS2, it is like programming a ne game since the way PS2 games are programmed and such are totally different from the PS1, plus they would have to do a lot of work on the graphics.
A movie would take even longer, since they would have to adapt the script, and soo much would be left out. Think how long it takes to beat the game, then try to make that into a movie. Way to long, or cut 2/3 of the stuff out.
The sweetest FF remake would be FF Tactics. If they remade it it would own FF7. FF7 had a sweet ass story line but tactics had better. The only thing that would own tactics if they remade it would be the materia system on FF7. Also, on tactics there is a massive amount of weapons compared to FF7.
