Drop is one of those thrillers contained in a single location. In this case it’s also contained by a single piece of technology. A woman on a date gets Airdrops, although they call it digidrop in the film, from a killer threatening her son at home. It’s like Phone Booth with Airdrops.
Now on 4K, the lavish rooftop restaurant shines, but the lighting is what really takes advantage of 4K range. The film fades to black except for a spotlight on Meghann Fahy. Throughout the film there are degrees of light fades in between the fully lit restaurant and the fully darkened effect. Her flashback to her abusive husband also boasts ominous shadow.
The surround sound gives you warped static sounds as she’s receiving the drops, and some car stuff at the end.
Bonus features showcase the stunt rigs and the elaborate building and stocking of the restaurant.
Director Christopher Landon gives a full commentary. Surprisingly the opening titles were all practical explosions. It’s interesting that they put all the phone graphics on the phones, not adding them in post-production. Choosing and clearing the memes she’s sent is another interesting detail, and Landon does address those lighting changes I noticed.
