LONDON — The cameras were rolling even before the actors Ryan Reynolds and Rob McElhenney could be sure there would be anything to film.
Last November, Reynolds and McElhenney were waiting anxiously to discover if their bid to buy Wrexham, a Welsh club marooned in the fifth tier of English soccer, would survive a vote from the Supporters’ Trust, the fans’ group that had rescued the team from bankruptcy and run it on a threadbare budget for years.
The actors had reason to be confident: When they had presented their ideas to the Trust in a video call, the reaction had been positive.
