NOTE: Hollywood Poker is now closed. Their players were transferred to redkings (another site on the ongame network) in 2012. Hollywood Poker is part of the OnGame network of sites. Hollywood poker is unique in that hollywood celebrities can sometimes be found at the tables.
While not the biggest site out there, being small has its advantages. Tournaments finish quicker, the loyalty scheme is more generous and they have fast and friendly live support.
Of special note are the celebrity bounty tournaments. There are 3 per week where you can attempt to outplay (or suckout on) celebrities or HP models for bounties ranging from $25 (for knocking out 1) to $2000 (for knocking out 5 in the $22 tournament) - (update 3rd May 09: unfortunately the celebs have changed and these sort of KO prizes are no longer available, there is a new points system in place).
While it doesn't have as many players as PokerStars or Full Tilt there are still some big tourneys such as the 'ChampionChip' $250,000 guarantee or the $100 rebuy, $100,000 guarantee. There are also some nice 50-100 man tourneys and a range of qualifiers where things seem a little more manageable than on the other sites.
While you can't choose your own character, Hollywood's look and feel is great with each player taking on the persona of a sterotypical Hollywood player ranging from old gran to big beefy dude. I don't know why but of all the poker sites i've played on I like the look and feel of this one the best.
A full table at Hollywood is 10 players whereas the other sites have 9 players. This means making final table at Hollywood is getting into the top 10 (which I prefer).
Hollywood has been regularly improving their software but unfortunately the new p5 engine is a bit of a mixed bag. This should become less of a problem over time as some of the issues are ironed out and players' computer hardware improves.
The loyalty program is good with players able to trade their poker points for tournament tickets and bonuses (among other things). I am always working off a bonus on Hollywood unlike the other sites that haven't offered me any bonuses for a long time. [Update 29th Jan 2009 - OnGame have revamped their bonus system this year and to cut a long story short it is not as generous as before, this is a bit of a shame as their bonus system used to be one of the best around.]
Live support is also great for getting your questions answered straight away. Definately a good place to start playing poker.
