Former hostage John McCarthy has criticised some of the scenes in hit US war drama Homeland, saying the plot is 'ridiculous'.
The series is about to return on Channel 4 for a second season after proving a huge success and scooping several Emmy awards.
Homeland is about US marine Nicholas Brody, played by British actor Damian Lewis, who is captured by militants in Iraq and apparently turned by them.
Despite its popularity McCarthy, who was held hostage for five years by extremists in Lebanon, has voiced concerns about elements of the plot.
He hinted that he disapproved of the scenes in which Brody appears to have flashbacks of beating a fellow marine to death to appease his captors.
He told the Radio Times: 'My concern is that, with the flashbacks and hints and really horrible violence we see, his conversion is almost like titillation - let's keep watching... did he really kill his comrade?'
He said of the flashback scenes: 'It all seems so mad, the whole bloody plot. It seems ridiculous.
'But watching someone being beaten to death in that way, even in the fairly snippety - it is absolutely grotesque and makes your stomach churn.'
