This is one of my favorite actresses. I thought I'd collect all the various bit and pieces I have found out about her on the Internet, and especially clips of her various roles on YouTube and such. She's a little-known actress, and that dovetails with my love of the obscure. Anyway, since I enjoy whatever I find out about her, I thought it'd post some of the things I have found.
She is best known (and almost only known) for her role as Donna in a few Cheech and Chong movies. They are usually a shorter role, with one or two scenes. Things are Tough All Over (1982), Nice Dreams (1981), Cheech and Chong's Next Movie (1980). My favorite is Nice Dreams where she has a her longest part and her most plot-central character, although the Next Movie is very memorable as well. Tough wasn't very impressive at all; a much smaller bit role; a let down, but not her fault.
WARNING: some crude humor and even brief topless nudity (it is Cheech and Chong, after all)
Ms. Guerrero also played Mrs. Ramirez on a family sitcom back in the 80s, The Facts of Life, appearing in one episode entitled "Adventures in Baileysitting" (She only appears in the last 1/4 of this clip about timeindex 5:20) (sadly, this is one of her better performances, but on the plus side she is stunning even in her minor role)
She was also a character named Maria in what looks like a low-budget horror movie in 1978, The Toolbox Murders. I haven't seen it, and not sure I want to, but apparently it's a highly exploitive, masochistic, erotic little slasher film, actually with a few "famous" scenes. Stephen King reportedly had a few nice things to say. Reportedly it was originally one of the 'Video Nasties' that was banned in 1982, whatever that means.
It appears to be a very small role. Lucky I suppose, considering the type of movie.
More importantly, she had a bit part in the premiere episode of Star Trek: The Next Generation "Encounter at Farpoint" but only part 2. It took me a while to find this, but she is the ensign who shows newly transferred Riker how to use the shipboard computer to locate Data at about timeindex 4:18 in the clip I have linked to here.
In the Star Trek clip, she isn't very attractive to me, I will be blunt. Close-cropped hair and masculine clothing. Don't just look at this clip! ;-)
more info that I have collected: Evelyn is currently the widow of Pat Morita (Mr. Miyagi in "The Karate Kid", the first Asian-American to be nominated for an Oscar). They were married later in life, Morita's fourth marriage on March 26 1994, and then Morita died in 2005 at age 77.
I can't say that it's true, but I found this info:
Evelyn and Pat first met when she was 15 years old because Evelyn's mother and Pat had the same manager, Sally Marr. Years later, Pat and Evelyn met again.
Evelyn (Evie) Louise Guerrero: born February 24, 1949 in East Los Angeles, California.
Evelyn had a pictorial in Playboy magazine in the 80s, and also appeared in the sexually-explicit musical comedy "Fairy Tales"
Oh, and this is all "to the best of my knowledge" jaja
