The first three URLs look normal; they’re off-site links for more information about the movie. The fourth URL, for “Discuss it!” is a form submission. Everything after the question mark is sent to a computer program on that server; the computer program decides what to send back based on that query. Each part of the query is separated by an ampersand (&). Special characters, such as spaces, need to be specially encoded, because special characters aren’t allowed in URLs. Often, these queries result in the server “querying” a database and returning the results of that query. (Here, it queries their database of discussion group postings.)
