It certainly couldn't be that much. "Bad Hat Harry Productions" is apparently Bryan Singer's television production company. It may have been making decent cash doing "House" on a seasonal basis, but "House" has been long since cancelled. And he'll get one directing fee and one directing fee only for directing the "Munsters" pilot.
If "Bad Hat Harry Productions" is a physical film studio / corporation occupying acres of land somewhere, it certainly couldn't be doing that well with television projects scant and far between. (It certainly wouldn't be making enough money to pay the property taxes on the land.) Not with Bryan Singer at the helm of this production company.
Bryan Singer certainly hasn't enabled "Bad Hat Harry Productions" to branch off into theatrical films (a massive source of income) because he keeps dropping out of (or is dropped from) movies he keeps announcing as the director:
1. Battlestar Galactica
2. Logan's Run
4. X-Men: Last Stand
5. Six Billion Dollar Man
Perhaps it's more likely that Bryan Singer's "Bad Hat Harry Productions" is an embryonic idea or mere moniker that Bryan Singer attaches to the rare projects he does manage to complete.
