Lazopoulos joined the Free Theatre of Athens, where he performed Why People are Happy, followed by yet another successful revue, Change and Craze.

In 1989 he staged "Greece after heart surgery" which broke records, while his following play "There was a Small Ship" ran for two successive years and was a box office hit.

Deka mikroi Mitsoi also took part in the festival of Forte dei Marmi in Italy, receiving an Honorable Distinction.

During that year, Walt Disney Productions assigned him the supervisory role of the animation film Hercules, for which he provided his own adaptation from English to Greek.

In the summer of 1999 he played the lead role in the film Beware of Greeks Bearing Guns directed by Australian director John Tatoulis.

Between 2003 and 2004 he wrote, directed, and starred in the revue "Wind in our Sails", which was presented at the theatre Britannia in Athens to commercial success.

The play toured Greece, culminating in a special performance at the ancient theatre of Epidaurus, as part of the Athens Olympics that August.

The winter of 2004 to 2005 found Lazopoulos writing, directing and starring as the lead in another successful and original production at Athens' Britannia theatre, "Where is this Bus Going?"

The premiere of Al Tsantiri Newsel [el] ("Live from the Shack") in November 2004 made Lazopoulos the first actor in Greek television history to host his own weekly show.

Since 2004 he has held the position of Programming Director for the entertainment sector of the privately owned television channel, Alpha TV.

The television program "504KM North of Athens", inspired by student life in Greece, was a project through which he was able to introduce a group of young actors and a talented new director to Greek audiences.

In the summer of 2005 Lazopoulos was set to once again bring his own style and interpretation to another Aristophanes play, The Acharnians this time for The National Theatre of Greece.
