Tiago Leão was born as a fimmaker and screenplayer. In 2005, he has co-directed, together with Laura Silleras, his first fictional short film, titled Poker. His passion for documentary arrives when he studies with Margarida Cardoso, Ateliers Varan and directors Catarina Mourão and Catarina Alves Costa.

The documentary is the narrative form he prefers, in order to tell stories with social and cultural contents. He realizes Ciganis, living for three months with a Gypsy family in Southern Portugal.

In 2007, he emigrates to Madrid and works for the production company Documentales Tus Ojos. Here, he works with screenplayer Alicia Luna to the project Bellezas Vacías. In the same year, he is invited by Magik Sound Productions to co-direct a biographical documentary on life and work by Henrik Takkenberg, dead in 2006, and co-founder of Chambao band. Simultaneously, he starts to prepare his project Longing Nights.
