If you are as much of a fan of Big Brother as me, you might be wondering who the 20 former houseguests that we will get to vote on might be.

So I took that 30 second commercial and watched it frame by frame to see who they showed.   I also looked up every contestant from every season and have listed it.  I saw 24 former HGs (by my count there have been 76 total HGs). 
 

Here is a run-down of every season's contestants.... (bold names were in the commercial). Season 1: Curtis, Jamie, Jordan, William, Eddie, Karen, Josh, George, Cass, Brittany. Season 2: Nicole, Will, Monica, Hardy, Bunky, Kristin, Kent, Mike Boogie, Shannon, Autumn, Sheryl, Justin. Season 3: Lisa, Danielle, Jason, Amy, Marcellas, Roddy, Gerry, Chiara, Josh, Eric, Tonya, Lori.

Season 4: Jun, Alison, Robert, Erika, Jee, Jack, Justin, Nathan, Dana, David, Amanda, Michelle, Scott 
Season 5: Drew, Diane, Michael, Jennifer, Karen, Marvin, Adria, Natalie, Jase, Will, Mike, Holly, Scott, Lori.
Season 6: Ivette, Maggie, Janelle, April, Howie, Beau, James, Rachel, Jennifer, Kaysar, Sarah, Eric, Michael, Ashlea.

Not surprisingly we only saw George from season one (the current producers were not involved in season one).  Ans there was a heavy dose of Season 4 & 5 contestants.

The least known contestants seen were Ashlea (voted out first in Season 6) and Lori (voted out 2nd in Season 5).

Of the 24 HGs seen, a few were barely in the commercial so I would be willing to guess these folks may not be in the show at all (and this assumes the main faces shown will), Sheryl, Nicole and Will (Season 5).

Keep checking my Big Brother 7 page as I will be updating it several times a day once Big Brother 7 begins.
