When a series has been on the air a long time, it's fun to look back at the guest stars who have helped make the show a success.
It's no surprise that CSI was loaded with some of the best entertainment has to offer. We're bringing them to you in the following slideshow. Every network, genre and generation is covered. You can count on it.
Just sit back and enjoy photos from actual episodes of the series for a walk down memory lane as we say goodbye to one of television's greats.
Krista Allen as Kristy Hopkins - "Pilot" - 2000
Krista Allen played prostitute Kristy Hopkins in three episodes of CSI in it's premiere season, beginning with its pilot!. Don't get too attached. She unwittingly makes a connection with Nick, and after sleeping with him in CSI Season 1 Episode 13 becomes the subject of a murder investigation. Oh no!!
Milo Ventimiglia as Bobby Taylor - "Friends & Lovers" - 2000
Milo Ventimiglia turns up as a suspect and eventual killer of his best friend in this heartbreaking performance on "Friends & Lovers," CSI Season 1 Episode 5. Look at those tears!
Dakota Fanning as Brenda Collins - "Blood Drops" - 2000
A teeny weeny little Dakota Fanning was at the heart of a family massacre story on "Blood Drops," CSI Season 1 Episode 7, when she guest starred as Brenda Collins in 2000. A sad tale of murder and sexual abuse, her face sure belies the tale!
Shawn Christian as Patrick Haynes / Chad Matthews - "Table Stakes" - 2001
Hey! Days of Our Lives star Shawn Christian got down and dirty when his sister (who he was passing off as his wife) killed a woman on "Table Stakes," CSI Season 1 Episode 15. Whoopsies!
Aldis Hodge as Tony Thorpe - "Too Tough to Die" - 2001
Aldis Hodge played Tony Thorpe in CSI Season 1 Episode 16, "Too Tough to Die," a role he'd later reprise in 2008. Talk about a long wait to return! Pretty cool though. His character was a murderer and rapist, who was used by the victim's husband years later to justify pulling the plug on his brain-dead wife.
Brigid Branaugh as Tammy Felton - "Face Lift" - 2001
Bridgid Branaugh was on two episodes of CSI. In the first, "Face Lift," CSI Season 1 Episode 17, she's discovered to have been a woman who was kidnapped as a small child and raised as someone different. In the next, CSI Season 2 Episode 9, "And Then There Were None," she's murdered. Multiple episodes of CSI are bad on guest stars!
