THEME: Das Booting— film titles have -ING affixed to the end, creating wacky "adaptations" (clued wackily): 

Theme answers:

• "LA LA LANDING" (18A: "Film adaptation with ... a choir arriving at the airport? (2016)")(this is the only clue with quotation marks around it in my version; I don't know why. Might be a software glitch on my end? No biggie.)
• "JURASSIC PARKING" (39A: ... a triceratops trying to find a sport for its car? (1993))
• "KNIVES OUTING" (52A: ... a quick trip to purchase cutlery? (2019))
• "KILL BILLING" (61A: ... a movement to make invoices illegal? (2003))

Word of the Day: ACC (36D: Louisville is in it, in brief) —

The Atlantic Coast Conference (ACC) is a collegiate athletic conference located in the eastern United States. Headquartered in Greensboro, North Carolina, the ACC's fifteen member universities compete in the National Collegiate Athletic Association (NCAA)'s Division I. ACC football teams compete in the NCAA Division I Football Bowl Subdivision. The ACC sponsors competition in twenty-five sports with many of its member institutions held in high regard nationally. Current members of the conference are Boston College, Clemson University, Duke University, Georgia Institute of Technology, Florida State University, North Carolina State University, Syracuse University, the University of Louisville, the University of Miami, the University of North Carolina, the University of Notre Dame, the University of Pittsburgh, the University of Virginia, Virginia Polytechnic Institute and State University and Wake Forest University.

ACC teams and athletes have claimed dozens of national championships in multiple sports throughout the conference's history. Generally, the ACC's top athletes and teams in any particular sport in a given year are considered to be among the top collegiate competitors in the nation. Additionally, the conference enjoys extensive media coverage. With the advent of the College Football Playoff in 2014, the ACC is one of the "Power Five" conferences with a contractual tie-in to a New Year's Six bowl game in the sport of football. (wikipedia)

Short write-up today—it's my last day of teaching for the semester and ... well, I don't know why that should make the morning feel particularly crowded, time-wise, but it does. Gotta make a good last impression! I don't really know what's going on with this theme. It's so simple, so basic, so conceptually last-century, that I think I must be missing something. You just add -ING to movie titles, with wacky results. Seems like you could do this forever, with wacky results. The problem is that the wackiness really varies, and most of it doesn't extend nearly as far into the realms of wackiness as it needs to for a theme like this to be successful. Maybe the idea of a driving dinosaur is wacky enough, but the others don't elicit laughter or wonder or much of anything beyond, "oh, ok, I see." The "adaptations" that result from adding -ING to these titles aren't even GROAN-worthy. You're asking me to imagine booking hotels and paying bills, why? These are the parts of my life I come to crosswords to forget. GREEN BOOKING is just plain dull. I like remembering movies as much as the next solver, but that's all this theme made me do. The wordplay just didn't feel up to snuff, especially for a Thursday, where things are supposed to get splashy and saucy and maybe even sexy, gosh darn it! KILL BILLING? You've taken a catchy, evocative, accurately descriptive title and made it about the most boring kinds of financial transactions? You're going the wrong way with your wackiness, man.
