Gaspard Ulliel plays the adult Hannibal Lecter in Hannibal Rising, the young man who reaches Paris and his aunt, Lady Murasaki. The Czech Film Commission announced his casting in September 2005 and described him as a 20 year old French actor. In February 2007, Ulliel told UPI that he had worried about following Anthony Hopkins in the role and that he wanted his Lecter to be more sympathetic than in the earlier films.
Aaran Thomas plays Hannibal Lecter (young), the title character as a boy. TMDB bills him second in the Hannibal Rising cast, directly after Gaspard Ulliel, who is credited as Hannibal Lecter. The credits therefore list two actors for the same character, with Thomas as the boy and Ulliel as the adult Hannibal.
Gong Li as Lady Murasaki
Gong Li plays Lady Murasaki in Hannibal Rising, the aunt Hannibal seeks out in Paris after he escapes the orphanage. Voice of America described the character as his Japanese born aunt by marriage. Gong Li told VOA that Murasaki sees early on that something is wrong with her nephew and tries to teach him the warrior spirit of Bushido, but his thirst for revenge moves beyond her control.
Dominic West as Inspector Popil
Dominic West plays Inspector Popil in Hannibal Rising, the French police inspector who investigates Hannibal in Paris, and is billed fourth on TMDB. The Czech Film Commission's production page names three cast members (West, Gong Li and Gaspard Ulliel) and records filming in the Czech Republic from October 2005 to January 2006.
Rhys Ifans plays Vladis Grutas in Hannibal Rising, the leader of the band of looters who shelter in the Lecter family's hunting lodge in 1944 and the main villain of the film. Voice of America called his character the brutal ringleader of young Lecter's captors. Ifans was one of the principal cast members the Czech Film Commission named in September 2005, a month before filming started in Prague.
Richard Brake plays Enrikas Dortlich in Hannibal Rising, one of the band of looters led by Vladis Grutas, and is billed sixth on TMDB. The Czech Film Commission's announcement of September 12, 2005 listed Brake in the principal cast with Gaspard Ulliel, Gong Li, Rhys Ifans and Kevin McKidd. Filming was set to start in Prague on October 10 that year.
Kevin McKidd as Petras Kolnas
Kevin McKidd plays Petras Kolnas in Hannibal Rising, one of the looters around Vladis Grutas, and is billed seventh on TMDB. The credits also give Kolnas a family: Robbie Kay plays Kolnas's Son, Vanesa Novakova plays Kolnas's Daughter and Beata Ben Ammar plays Astrid Kolnas. McKidd was one of the five actors the Czech Film Commission named in September 2005 for the Prague shoot.
Stephen Walters as Zigmas Milko
Stephen Walters plays Zigmas Milko in Hannibal Rising, one of the looters led by Vladis Grutas who shelter in the Lecter hunting lodge in 1944. TMDB bills him eighth, between Kevin McKidd and Ivan Marevich. Each looter is a separate named role, and Goran Kostić is credited further down the list as Kazys 'Pot Watcher' Porvik.
Ivan Marevich as Bronys Grentz
Ivan Marevich plays Bronys Grentz in Hannibal Rising, a member of the band of looters led by Vladis Grutas, and is billed ninth on TMDB. He closes the group of looters billed directly after Rhys Ifans. Ifans, Richard Brake, Kevin McKidd, Stephen Walters and Marevich fill fifth to ninth place in the credits, and the actors playing the Lecter family are billed next.
Helena-Lia Tachovská as Mischa Lecter
Helena-Lia Tachovská plays Mischa Lecter in Hannibal Rising, the little sister of Hannibal Lecter. She and Hannibal are the only survivors when a Soviet tank wrecks the family's refuge, and her death in the winter that follows sets up the rest of the story. TMDB bills her tenth, the first of the three Lecter family roles that come after the looters in the credits.
Richard Leaf as Father Lecter
Richard Leaf plays Father Lecter in Hannibal Rising, head of the family living in the castle in 1944 Lithuania as the war reaches the Baltic region. Early in the film, the family flees to a hunting lodge in the woods. TMDB bills Leaf eleventh, between Helena-Lia Tachovská and Ingeborga Dapkūnaitė, so the three family roles appear together in the credits.
Ingeborga Dapkūnaitė as Mother Lecter
Ingeborga Dapkūnaitė plays Mother Lecter in Hannibal Rising, the mother of Hannibal and Mischa in the 1944 opening. Lithuania's public broadcaster LRT describes Dapkūnaitė as a Lithuanian actor, so the film's Lithuanian prologue includes an actor from Lithuania. She is billed twelfth on TMDB, the last of the three Lecter family roles, which begin with Mischa.
