There is no Hollywood person that I have more respect for than Joss Whedon. Nearly everything he touches (that I have seen) is absolutely brilliant.
You may know him as the guy who created Buffy the Vampire Slayer and Angel. Or as the guy who created Firefly, a show that was canceled way too early, to put it lightly. For more recent stuff, he’s the guy who produced Agents of SHIELD and directed both The Avengers and Avengers: Age of Ultron.
To top that off, he also directed a couple episodes of my favorite TV show, The Office, was one of the writers of the Toy Story screenplay, and did the whole shebang on a modernized version of Much Ado About Nothing, which he filmed at his home, since he’s a huge Shakespeare geek.
(If you haven’t seen Much Ado and are a fan of Buffy and Angel, I encourage you to check it out–if you have Amazon Prime, you can watch it for free. Alexis Denisof and Amy Acker are the leads and if you were crushed by the Wesley/Fred storyline on Angel, then this will make you immensely happy.)
Oh yeah, he has also written some comic book series, including Angel: After The Fall, which takes place after the show was canceled, plus created the Astonishing X-Men.
Can you see why I included him in my nerd life theme? This guy rocks almost every single aspect of it.
