“I write, therefore I exist” said fetus Mariana M. Sierra on the day she was born, the luckiest day of March, the 13th. Raised in Mexico City, she graduated with a Bachelor degree in Communications with specialization in Film at the prestigious Universidad Iberoamericana. She’s fluent in Spanish and English. She learned to pull ideas from her brain with a couple of tweezers and put them onto a page where she would feed them and raise them…or even kill them.

One of those ideas survived through the end of her studies when she wrote and directed her first short film in 2019, titled “Toro” (Little Bull in Spanish). A mockumentary about a kid with horns in Mexico City dealing with a life on the streets, looking for his parents. It became a semifinalist short film in the Serbest International Film Festival in 2022.

She collaborated on other short film ideas like “SIA” and the web series “Kidnapped Love”. Based on research made by Exeter and Leeds University, she participated in the collaboration as a writer and director of the third episode, produced by VerdeAzul Producciones. This series portrayed the issue of kidnapping in Mexico and the struggles of the relatives of missing people.

After three years of video editing for Upsomedia, she took the next step on her film career by traveling to Canada where she graduated from the Writing for film, television and games program at Vancouver Film School.

She produced and co-directed “Phantom Frequency”, a comedy horror short film set to debut at film festivals. Mariana M. Sierra is thrilled that the ideas incubating in her head for years are finally traveling to an actual page where she is developing two feature film scripts. One of them, the feature film adaptation of “Toro”.
