Leiss's "subtle and sardonic manner" as "a self-amused teacher on the down-side of life" opposite Ann Shulman in
Educating Rita at the MIllbrook Playhouse Cabaret was hailed by critic Jim Runkle in 1985. Leiss played a painter in Franco Marinai's 1988 experimental film
Mock Gravity, which used hand-drawing on film stock for sequences representing flashbacks and the actors' thoughts, and it was
shown at 26th annual
Ann Arbor Film Festival, and chosen for the 1988 Melbourne International Film Festival. Leiss on return to Australia in 1995 was a co-founder of WAX Studios Inc. in
Richmond and over 1996–2000 designed the sets for
Cowboy Mouth (1997), and acted in productions including a September 1997
Harold Pinter double bill,
The Dumb Waiter and
The Lover of which reviewer Helen Thomson wrote:Peter Leiss as Ben and Robert Corner as Gus give fine performances, creating the complex rhythms, the unexplained gaps, the shocking ordinariness necessary to build up the play’s suspense and give its conclusion the maximum shock impact.
