<P> In the pilot episode, the name Wilkerson can be seen on the name badge of the uniform Francis is wearing at Marlin Academy . In the sleeve notes for the season 5 DVD released in Europe, the family is referred to as the Wilkersons in the description for the episode "Block Party". British television advertisements and some Fox promotional material also occasionally referred to the family as the Wilkersons, although this name was never spoken aloud in the series . In an early version of the pilot, Malcolm had an exchange of dialogue with a classmate, who claims to have overheard his parents talking about Malcolm's family and asks him what his last name is . When Malcolm responds, "Wilkerson, why?" the friend replied with the punchline, "Oh...who are the' Pariahs'?" </P> <P> Out of the show's six leads, Cranston, Berfield and Sullivan were the only ones to appear in all 151 episodes . </P> <Table> <Tr> <Th> Actor </Th> <Th> Character </Th> <Th_colspan="7"> Season </Th> </Tr> <Tr> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> 5 </Th> <Th> 6 </Th> <Th> 7 </Th> </Tr> <Tr> <Td_colspan="12"> Main characters </Td> </Tr> <Tr> <Td> Jane Kaczmarek </Td> <Td> Lois </Td> <Td_colspan="7"> Main </Td> </Tr> <Tr> <Td> Bryan Cranston </Td> <Td> Hal </Td> <Td_colspan="7"> Main </Td> </Tr> <Tr> <Td> Christopher Masterson </Td> <Td> Francis </Td> <Td_colspan="7"> Main </Td> </Tr> <Tr> <Td> Justin Berfield </Td> <Td> Reese </Td> <Td_colspan="7"> Main </Td> </Tr> <Tr> <Td> Erik Per Sullivan </Td> <Td> Dewey </Td> <Td_colspan="7"> Main </Td> </Tr> <Tr> <Td> Catherine Lloyd Burns </Td> <Td> Caroline Miller </Td> <Td_colspan="2"> Main </Td> <Td_colspan="5"> </Td> </Tr> <Tr> <Td> Frankie Muniz </Td> <Td> Malcolm </Td> <Td_colspan="7"> Main </Td> </Tr> <Tr> <Td> James and Lukas Rodriguez </Td> <Td> Jamie </Td> <Td_colspan="3"> </Td> <Td_colspan="1"> Recurring </Td> <Td_colspan="3"> Main </Td> </Tr> <Tr> <Td_colspan="12"> Recurring characters </Td> </Tr> <Tr> <Td> Craig Lamar Traylor </Td> <Td> Stevie Kenarban </Td> <Td_colspan="7"> Recurring </Td> </Tr> <Tr> <Td> David Anthony Higgins </Td> <Td> Craig Feldspar </Td> <Td_colspan="7"> Recurring </Td> </Tr> <Tr> <Td> Gary Anthony Williams </Td> <Td> Abe Kenarban </Td> <Td_colspan="7"> Recurring </Td> </Tr> <Tr> <Td> Evan Matthew Cohen </Td> <Td> Lloyd </Td> <Td_colspan="4"> Recurring </Td> <Td_colspan="3"> </Td> </Tr> <Tr> <Td> Kyle Sullivan </Td> <Td> Dabney </Td> <Td_colspan="4"> Recurring </Td> <Td_colspan="3"> </Td> </Tr> <Tr> <Td> Daniel Von Bargen </Td> <Td> Edwin Spangler </Td> <Td_colspan="3"> Recurring </Td> <Td_colspan="1"> Flashback </Td> <Td_colspan="3"> </Td> </Tr> <Tr> <Td> Will Jennings </Td> <Td> Kyle </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="1"> </Td> <Td_colspan="1"> Flashback </Td> <Td_colspan="3"> </Td> </Tr> <Tr> <Td> Drew Powell </Td> <Td> Drew Horton </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="1"> </Td> <Td_colspan="1"> Flashback </Td> <Td_colspan="3"> </Td> </Tr> <Tr> <Td> Arjay Smith </Td> <Td> Ken Finley </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="1"> </Td> <Td_colspan="1"> Flashback </Td> <Td_colspan="3"> </Td> </Tr> <Tr> <Td> Karim Prince </Td> <Td> Stanley Winn </Td> <Td_colspan="1"> Recurring </Td> <Td_colspan="6"> </Td> </Tr> <Tr> <Td> Eric Nenninger </Td> <Td> Eric Hansen </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="1"> Flashback </Td> <Td_colspan="3"> </Td> </Tr> <Tr> <Td> Merrin Dungey </Td> <Td> Kitty Kenarban </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="1"> Recurring </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="2"> </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="1"> </Td> </Tr> <Tr> <Td> Kasan Butcher </Td> <Td> Joe </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="1"> Recurring </Td> <Td_colspan="1"> </Td> <Td_colspan="1"> Flashback </Td> <Td_colspan="3"> </Td> </Tr> <Tr> <Td> Tania Raymonde </Td> <Td> Cynthia </Td> <Td_colspan="1"> </Td> <Td_colspan="1"> Recurring </Td> <Td_colspan="2"> Guest </Td> <Td_colspan="3"> </Td> </Tr> <Tr> <Td> Cloris Leachman </Td> <Td> Ida </Td> <Td_colspan="1"> </Td> <Td_colspan="2"> Guest </Td> <Td_colspan="4"> Recurring </Td> </Tr> <Tr> <Td> Emy Coligado </Td> <Td> Piama Tananahaakna </Td> <Td_colspan="2"> </Td> <Td_colspan="5"> Recurring </Td> </Tr> <Tr> <Td> Chris Eigeman </Td> <Td> Lionel Herkabe </Td> <Td_colspan="2"> </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="1"> Recurring </Td> <Td_colspan="1"> Guest </Td> </Tr> <Tr> <Td> Victor Z .
