I'm not really sure I can buy this argument about Danny Dyer's family being on the breadline.
I'm sure he's a really nice bloke, looks after his gran etc. After all he's a W*** H** fan, probably knew the Krays and say what you like about them, lovely fellas, always looked after their own...
I'm not saying they're on the breadline, I don't know. All I can go on, is DD's comment, he took sh*t jobs, just to earn some money. I don't know the man personally, so am in no position to disbelieve him. IMHO, I wouldn't say he was skint, but he's probably not a millionaire. Acting is a very unstable job, and the guarantee of a paycheck is too hard too turn down, when you've got a family.
A quick google search (if the website is reliable) states as of 2012 he had a net worth of about £50k. Not exactly on the breadline, but he's hardly in a position to turn down guaranteed paychecks.
