Zimler has also edited an anthology of short stories for which all the author's royalties go to Save the Children, the largest children's rights organization in the world. The anthology is entitled The Children's Hours. Participating authors include Margaret Atwood, Nadine Gordimer, André Brink, Markus Zusak, David Almond, Katherine Vaz, Alberto Manguel, Eva Hoffman, Junot Díaz, Uri Orlev and Ali Smith.

In 2009, Zimler wrote and acted in The Slow Mirror, a short movie based on one of his stories. Directed by Swedish-Portuguese filmmaker Solveig Nordlund, the short stars Portuguese actors Gracinda Nave and Marta Peneda. In May 2010, it won the Best Drama award from the New York Downtown Short Film Festival.

His penultimate novel, The Warsaw Anagrams, was chosen as 2009 Book of the Year by the main Portuguese book magazine Ler and by the country's high school teachers and students (the 2010 Mariquis de Ouro prize). It was also chosen as one of the 20 Best Books of the Decade 2000-2009 by the country's foremost daily newspaper, Público. In August 2011, the San Francisco Chronicle described the book as follows: "Equal parts riveting, heartbreaking, inspiring and intelligent, this mystery set in the most infamous Jewish ghetto of World War II deserves a place among the most important works of Holocaust literature."In August 2011, Zimler published his first book of poetry: Love's Voice: 72 Kabbalistic Haiku. The verses in the book express Jewish mystical ideas and imagery in the form of haiku.

Zimler has written two children's books that have been published in Portuguese: Dança Quando Chegares ao Fim and Hugo e Eu e as Mangas de Marte.

Zimler has lived with Portuguese scientist Alexandre Quintanilha, 11 years his senior, since 1978. The two met in San Francisco in December 1978. They were married in August 2010, when same-sex marriage was legalized in Portugal. They have lived in Porto, Portugal since 1990.
