Coronation Street star Kym Marsh has spoken about the soap's upcoming mini-bus crash storyline. The actress recently appeared on BBC Breakfast and spoke about how the "challenging" crash storyline is connected to Steve McDonald's depression. Kym said that the filming process was tiring but the end result was worth the effort. Kym pictured earlier this year "We have actually spent a lot of time on that and we were all quite exhausted by the time we finished filming it, but it's amazing. It's a great storyline and a challenging one. "It is linked to Steve and Michelle and Steve's depression as well, so there's more to come from that. It's very dramatic. "I actually stayed behind to watch the stunt and it was brilliant". The 38-year-old also talked about her character Michelle O'Connor, saying that she is "confused" by Steve's recent behaviour. "She's just so confused by him at the moment. "Nobody knows that he's suffering from depression, so he's just behaving so oddly and of course they've split up now. She just thinks it's her". Kym and Simon in character as Michelle and Steve Kym, who recently became engaged to her boyfriend Dan Hooper, said that initially she and Simon Gregson, who plays Steve, wondered if he was the right character for this storyline. "I think when we first found out we were doing this story with Steve, both Simon and I were a bit like, 'Is Steve the right character to do this?' "But the more we thought about it, the more we thought, 'He is absolutely the one who should be doing it'. "He's such a jovial character and so upbeat all the time and joking. "It's showing people that if somebody like Steve McDonald can have depression, it can happen to anybody at any time".
