Okay, here's another one, guys. Ever heard of a dude called Calum Waddell? He's a 'writer/producer'. He makes a lot of special features for like, obscure horror films and that sorta thing. Anyway, just looking on his twitter feed or reading one of his articles about a movie should tell you enough about this guy not only having a massive ego but also being a massive tool.
He's actually become quite notorious in the indie horror scene for being egotistical, rude and arrogant as all hell. He frequently argues with people online if they call him out on his ill-informed opinions or just minor disagreements in regard to anything he's written and once he runs out of arguments he uses the typical 'you must be a troll in your mum's basement lul'.
There's a company dedicated to releasing obscure horror etc called Arrow Video; whom he used to work for. Nowadays all he does is bitch about them obsessively, even going so far as to leak their new releases and criticize them publicly on almost every one of his social media accounts. To boot, he will brag about how he's the reason some of the movies get the attention they do today.
As well as this, he googles his name daily, nightly and ever so rightly and will almost always make a show of it on twitter if he finds anyone saying anything bad about him.
He's a lot of work to find out about but once he gets going he's a total prat. I wouldn't be surprised, to be honest, if he finds this thread and bitches about it on his twitter or tries to sue or whatever.
Here's a link to a thread that briefly documents how he tried to sue a dude for making a throwaway comment about him in an article -
