" Merlin star Angel Coulby has suggested that the show will end after five years. The fourth series of the fantasy drama begins this Saturday on BBC One, while a fifth run has already been commissioned. &amp;quot;They&amp;#039;ve always said they would do five [years], so apparently... next year&amp;#039;s the last one,&amp;quot; she told Digital Spy. &amp;quot;[It&amp;#039;ll be] five apparently, in total.&amp;quot; Coulby also revealed that she was not surprised when Merlin was renewed, despite the fourth series not having aired. &amp;quot;I kind of expected it,&amp;quot; she admitted. &amp;quot;I think it&amp;#039;s been such a success that it would seem mad not to continue it out to its end.&amp;quot; Merlin co-creators Johnny Capps and Julian Murphy recently revealed that a film version of the hit series is also in the works. Merlin returns to BBC One this Saturday at 7.50pm. &amp;amp;gt; Merlin: Ten teasers about the series four premiere Watch Angel Coulby&amp;#039;s full interview with Digital Spy below:      "^^<http://www.w3.org/2001/XMLSchema#string>
