The 33-year-old, who has joined the cast of the hit US TV show to replace troubled actor Charlie Sheen, is winning over the cast and crew, despite initially annoying them by having a huge trailer.
A source told US gossip website TMZ.com: 'Everything so far is smooth. A little too soon to tell, but Ashton seems very likable and professional. We're all very happy to be working with him.'
Kutcher, who plays Internet billionaire Walden Schmidt in the programme, had previously rolled on to set with a massive trailer, which angered some Sheen fans who thought it was 'over the top'.
