The makers of the documentary about the life of Pogues singer Shane MacGowan have decided to add subtitles after reviewers said it was hard to make out what the singer was saying.
Crock Of Gold: A Few Rounds With Shane MacGowan director Julien Temple said he accepted the "strange mixture of Irish and English" could be tricky to make out.
Speaking to the BBC, Temple said: "We certainly knew that in the States we would have to possibly subtitle it. In the end it is a decision for the distributors to make."
The documentary maker, also known for having made films about The Sex Pistols, Joe Strummer and the Glastonbury Festival, won the special jury prize for Crock Of Gold, which is out this Friday, at the San Sebastian Film Festival.

This time around it is the life of the Fairytale of New York hit-maker and his band that is explored.
Johnny Depp is one of the producers and interviewers of MacGowan in the documentary and the BBC asked would his role be cut.
"He was very important as the producer on the film, making it achieve conclusion," Temple said.
Sinn Féin president Gerry Adams, and Primal Scream's Bobby Gillespie also interview MacGowan in the film.
The Pogues recently made headlines when BBC Radio 1 announced it would play an edited version of Fairytale of New York, the band's 1987 duet with Kirsty MacColl, because the festive favourite contains lyrics that some listeners may find offensive.
The song re-entered the UK top 30 for the 16th year in a row on Friday, and is currently at number 26.
The documentary will be released in cinemas in Ireland on Friday December 4th. Look out for our review of the film and interview with Julien Temple later this week.
