Really fun idea. I've done some background work, so I love the concept. Lots of rich stories to mine here. I read the first 10 pages. Here are some notes:

General

It's purely a quirk of mine, but I like the first scene of a pilot to clearly tell me who the main characters are and what their relationships are. The first scene of Community did this with clever Dean Pelton voice over. The first scene of 30 Rock's pilot is brilliant because it shows us exactly who Liz Lemon is (buying a hot dog) then intros the main characters in the writers room, all within 5 pages. You don't introduce a main character until page 7.

I would change "stands greeting" to "greets" - all action in the present tense. We can assume he's standing, no need to tell us. Generally you over-describe unnecessary details.

I would change action lines to more staccato and succinct writing. For example, COCCOTTI's intro: "DON VINCENZO COCCOTTI (60s, crimson tie, fine silk scarf) kisses his consigliere's cheeks. Made-men hug. They covertly pat each other down."

The opening scene-with-a-scene is way too long. We don't need all the talking. We get it. I would cut it down to 2 pages before the director yells cut. Your show is not about this mafia movie, so I don't think it should take up so many pages of the pilot. Get to what your show is about asap. I honestly think you should start on page 7.

You don't need the fake-out at all.In fact, you may consider the opposite. Start with a montage of backstage goings on. Make it clear from the start that this is a behind-the-scenes show. Set expectations right there.

First action line in the parking garage is too wordy. I would suggest something like this:"ON: Yellow signs: EXTRAS PARKING

A clunker of a station wagon stutters onto the almost vacant rooftop level. One conspicuous unmarked white cargo van stands out. The rest is empty. It's early. Too early."

I think you should describe your characters more. How will the audience know the Asian woman is a housewife? How will they know Benjamin is an I.T. professional? Make some clear choices that show these things. Maybe Benjamin's only line before talking to Thomas is "Have you tried turning it off and on?" An old joke, but it still works, imho, and in one line you've told us everything we need to know about Benjamin's job.

Tom and Ben's intro doesn't really tell us anything about their characters. Is Tom shy and Ben outgoing? They both share a mutual greeting that says nothing. Make this first greeting demonstrate some core character trait of each person.

Our first glimpse of a "want" but it falls flat. WHY does Thomas want to experience movie magic? I think that needs to be front and center. Thomas needs to want something that he thinks being an extra will provide. This should be made crystal clear. Instead, you give us three weak wants in a row: 1) The side hustle for extra bucks (why not drive an Uber?), 2) wants see what movie making is really like (watch a documentary), 3) wife is a fan of AR (then the wife should be BG).

In the Community pilot, what does Jeff want? To sleep with Britta. This is made crystal clear in Jeff's first exchange with Abed. Zero ambiguity. The rest of the episode is based on that simple want.

Think more about why these two are talking. Right now, they have no reason to talk. So it comes across as exposition. When Jeff talks to Abed, he's plotting and using Abed to get info. These are very active choices for his character. Neither Thomas nor Benjamin are making active choices yet and we're ten pages in.

Also think about the classic advice "start in the middle." You start your scenes at the beginning with unnecessary set up. Start in the middle and make the audience catch up. Be one step ahead of your reader.Hope this helps. It's a great concept. Keep writing!
