Marti is 5' 6" (1.68 m) tall.
When Marti got her job at Buffy the Vampire Slayer she immediatly phoned her mother, getting the reply: "I'm sorry dear. You'll do better next year".
Many of the fans of Buffy the Vampire Slayer had a big dislike of the series' two last seasons, and many fans blamed Marti's growing responsibility for this, but Joss Whedon has stated that they had equally much responsibility in the shaping of the Seasons, and that they did exactly what they wanted to do.
Joss Whedon, creator of Buffy the Vampire Slayer once called Marti: "Marti - She of the great brain and great beauty"
When the WB television network accepted the Buffy the Vampire Slayer spin-off series, Angel, Joss Whedon, the creator and executive producer of both series, promoted Marti from writer to executive producer and gave her increasing charge of producing Buffy.
Besides her work on Buffy the Vampire Slayer, Marti co-wrote the 1999 movie Just A Little Harmless Sex, and wrote the pilot for Still Life in 2003, though the show wasn't picked up.
Marti has stated that she hates spoilers leaking out on the internet before the episode in question has aired. Not because of personal reasons, but because it makes the enjoyment of the fans worse.
Marti felt very intimidated because she had to write the episode following up the genius classic "The Body" on Buffy the Vampire Slayer. She has stated that it was really hard to follow Joss Whedon like that.
Marti's interest for writing started when she was still in school. Her father was a documentary filmer and she felt very early on that she wanted to do something similar. Her job as a writer on Buffy the Vampire Slayer was her first big job as a writer.
Marti didn't come to the Buffy the Vampire Slayer crew until the beginning of its second season, and was therefore not involved with anything in the show in Season 1. She has however stated, that she had to rewatch that season in order to get to know the characters.
Marti has sung in three episodes of Buffy the Vampire Slayer and Angel; as the Parking Ticket Lady in Buffy's "Once More With Feeling" and "Selfless", and as the "Cordy Theme" singer in Angel's "Birthday".
Marti graduated from UCSC in 1987 and named three of the fictional UC Sunnydale dorms in Buffy the Vampire Slayer (Kresge, Stevenson, and Porter) after Colleges at the University.
Marti: I definitely am drawn more to the darker side of things. The things I'm definitely drawn to are more melodramatic, and that's OK - we all have our favourites. It takes me a long time to write a good joke.
Marti (About her fellow writer Joss Whedon): Well, pathetically for all of us, Joss doesn't seem to have any weaknesses. We're still waiting...
Marti (About Buffy's 100th episode): I certainly didn't think I'd still be writing Buffy The Vampire Slayer, and I certainly didn't think that I'd be loving it and passionate about it into my 100th episode or close to it.
Marti: The episodes you see from me which have that kind of dramatic bent are just because that's where my writing was when I got here and I've had the opportunity to keep going in that direction. I'd love to do comedy and humour but, for me, it's not the first instinct.
