I had a hundred and one questions for Ridley and time for only 3. I've previously said I felt like I wasted that interview but I can guarantee you that I'd never have phrased any questions in that manner.
Think what we want about the man and the recent films but there's a certain decorum to this kind of thing. If you ever get the chance, however, good luck with those!
Any time you're on tape, be it video or audio, you'll critique yourself mercilessly. I think you conducted yourself well, given what a huge fan you are. Your Fox contacts should be relieved and will probably facilitate future such opportunities.
To illustrate how badly it could've gone, here's a true story: I'll never forget watching a fan interview of his favorite celebrity. All agog at the chance to talk to the guy, he asked, "So where do you see yourself and the band in five years", a typical but trite question. The look on that fan's face when the celeb responded, "Dead. All dead," (as he took an exasperated drag off his cigarette) was sad. I was embarrassed for the guy, since obviously he loved the band, but didn't think about how many times they're interviewed and how sick they get of the same old questions, or fan-gushing.
You avoided both.
Again, the attention Fassbender paid your questions was amazing. Scott looked tired, but F was rapt. Maybe that's just how he rolls, but you could've very well gotten barely-concealed contempt or something akin to the story I related.
