In 1964, Englert graduated from the Aleksander Zelwerowicz National Academy of Dramatic Art in Warsaw and started working in the Polish Theatre, where at first he mostly played supporting roles.

A breakthrough came in 1968 with the international success of Notes, produced by the Television Theatre, where he was noticed by Kazimierz Kutz and offered work in film.

To his frustration, Englert found himself being type-cast into roles of friendly, straightforward, honorable and unambiguous lovers.

In 1997 he started acting for the National Theatre in Warsaw and became its artistic director in 2003, a function which he has been fulfilling to this day.
