[citation needed] Since October 2008, Markl has worked for Antena 3, with his current shows being "São Coisas Que Acontecem", "Laboratolarilolela" (a showcase of lesser known Pimba artists and songs), and "Nuno & Nando" (with Fernando Alvim).

Before "São Coisas Que Acontecem", he ran "Há Vida em Markl" (based on a comic strip formerly published on Inimigo Público) and "O Livro dos Porquês" (where funny answers were given to mundane factoid questions).

[citation needed] Nuno Markl debuted on television in 2001, co-hosting "Sem Filtro" (a youth-oriented talk show on RTP1) alongside Rita Mendes and Gaspar Borges.

He wrote for the prematurely cancelled Programa da Maria (which had some Upright Citizens Brigade influenced sketches) and now writes for Os Contemporâneos.

Other side projects include TV and print ads for Café Delta and performing voice acting duties for the Portuguese version of films: He was also responsible for translating and adapting Monty Python sketches for an onstage Portuguese version, performed by, among others, Bruno Nogueira, Miguel Guilherme, António Feio and José Pedro Gomes.
