A common idiom is 'It's a closed shop.'

Although this applies in the first instance to trades unions and working practices, the expression is used far more broadly to describe a situation involving nepotism, elitism, selectivism and the like.

Such an example is this one from the Irish Times:

"IT MAY not be the largest trout competition but it’s up there with the best,” a sentiment echoed time and time again at last week’s vintner’s fly-fishing championship on Lough Mask in Co Mayo. While the world cup competition sets claim to the greatest number of anglers (460 this year), the vintners is an absolute gem. It’s a closed shop, by invite only. “There are 50 or 60 on the waiting list,” according to organiser Tom “Swanky” Sweeney.

And one from the IMDb message board:

The reality of getting a script from paper to screen is a gigantic step for known writers let alone unknown ones.

Hollywood is virtually a closed shop.
