Gary Barlow's new TV show Let It Shine is just one week away from the grand final but some viewers think there's a big problem.
The new BBC One talent series follows similar previous musical programmes with Andrew Lloyd Webber, such as Any Dream Will Do and Over the Rainbow.
Fronted by Gary, Let It Shine is following the hunt for singers to perform in a new touring musical based on the songs of Gary's band Take That.
The winners will perform in the production when it hits stages across the UK.
So far the contestants have been tested on their singing and this weekend they took on a dance challenge, but some fans have questioned whether any of the boys can actually act.
It's not quite clear how much acting Gary's new musical will require but as yet we've not seen the bands tested on even their basic abilities.
"Do you think they will mention the word "acting" #letitshine it's just a vital part of a musical? Is it not?" one of many comments posted to Twitter during Saturday's show read.
More Twitter comments (via OK!) included: “It’s the semifinal, and nobody has done an acting audition yet. Woop Woop. #LetItShine.”
A third asked: "So they can obviously sing & tonight they're showing dance moves but what about acting? Can these guys act? Surely that's needed #LetItShine.”
And a fourth posted online: "I wonder if these boys can act. That's kinda important in theatre. #LetItShine"
Maybe show bosses have something planned for the final?
Let It Shine concludes next Saturday night on BBC One.
