I always wonder what the story is behind the low numbered profiles. IMDb was originally developed in Cardiff, Wales and Bristol, England before growing in the behemoth it is now and owned by Amazon. To some extent the early numbers are alphabetical; Fred Astaire is #1 then the very early numbers are classic golden age of cinema actors. Rowan Atkinson appears at #100. John Carrol Lynch is #2253 but in the grand scheme of things, that's still very low number in the database. I can only assume that one of the initial developers was a fan of his early work.
