However, on 30 May 2007, Olejnik was released by Villa manager Martin O'Neill and the following day joined Scottish club Falkirk. At the start of the season, Olejnik became second choice to Tim Krul who made 22 appearances. Olejnik made his debut for the club in a 1–0 win over Kilmarnock on 2 January 2008, coming on a substitute for Russell Latapy after Krul got sent off for unsportsmanlike conduct. Krul would later return to his parent club after suffering a shoulder injury and Olejnik would later become a first choice goalkeeper for the rest of the season. Olejnik managed to keep his first clean sheet for the club in a 0–0 draw against Aberdeen on 5 January 2008.
