a view from 2 forms or different layout for same form

I need two solve a problem that I will explain with an example to make it more easy even because my English it's quite poor.
Here it is:
I have one form with two fields: the first is a drop down single choice with a list of movie, the second one is a multi line field where visitors can add a short comment of the movie.
This form will be embedded i 3 different page: the first one is dedicated to a movie, where all comments sent via the forms are listed (recalled via rss permalink), the second one is same as first for a different movie the third one is a resume for all the movies.
Now I'd like that in the third page the embedded form will show both fields (leaving the visitor the option to choose which movie to comment),but in the firs and second page I wont to show only the comment field or at list both, but with the right movie already selected in the first field (drop down one).
But how to obtain different formats for the same form when embedded in different pages? ("hide this field to others" option obviously doesn't get the right result in this situation)

another way I'm considering is:
built two different form (one for each movie) with only the multi line field for the comment.
But then I need a view that connect the two different forms, that display a column with the name of the movie and another one with the comment, giving me the option to recall (via rss again) the results, filtered as necessary in each page.
Is it possible to have a view that call records from different forms?

Hope to be clear enough, my real situation is more complex, but I made an easy example hoping to get a result.

Thanks for your job! I'm finally building a website where visitors can really interact, and this was not possible without your application, why I don't know a single line of php sql and bla bla bla! Thanks again

(I inform you that trying to reordering columns is always giving me an error that doesn't allow me to show the view in the order I'd like)
