In American party shows/films how they always just cart their beer around in a carton or dolphin killers and they're never in the fridge/on ice.
Dolphin killers when they use toy babies instead of real ones for a 5 second scene - yes, I'm looking at you American Sniper
Also, the KIA add where the bird is singing in the car, some scenes the toddler is in the backseat, others she isn't. Either she is, or she isnt, get with it directors
The use of Wilhelm scream or Howie scream in non-comedy films. Isn't so much a wink to the audience as a lazy cop out.
Pointless location subtitles Wide shot that shows Westminster, Tower Bridge and St Pauls 'London, England'
Changing the colour tint of a pretty typical actionfilm in post production to give it a grittier feel. Looking at you Man of Steel. Had the Wilhelm scream too.
Little kids with incredibly saccharine speaking roles. This probably started with that annoying brat at the end of Its a Wonderful Life but has been a feature of movies ever since.
The "too-clever-for-you" straight man. No the hetero kind, but that "comedy" type. Like Paul Rudd in Role Models or something.
Canned laughter. Seriously, why? If I don't know when to laugh then your show is not funny. Also, and I know I'm in the minority here - suspense. Just fucking get on with it will you. Seriously every modern horror could be done in 10 minutes.
American/British actors with shocking stereotypical accents for foreign characters. Any Sean Connery accent. (Still get a laugh out of his Highlander 'What's Haggis?' line to this day)
That's fine IMO. They are technically speaking in their own language in those movies, so it has to sound "natural" I guess? It's not like they are speaking English with Russian accents to each other.
